176 * 03.01.94 -- 3.05.95 Import and export of any number of channels works,
177 * except a small bug with margin handling when exporting.

236 * 30.11.94 -- 3.05.64 On demand grabbing of pending auto writelocks.

249 * Ugly seteuid bug in ForkWindow() fixed.
250 * 20.12.94 -- 3.06.00 Solaris has broken seteuid().
251 * osf loadav patches. -- DISTRIBUTED
252 * 08.01.95 -- 3.05.65 Bug with LOGOUTOK and -ln fixed. redundant secfopen()
253 * avoided, when logfflush() looks at delayed nfs updates.
254 * Option parser now allowes condensed options. -A fixed.

256 * -WdmS starts a detached screen session with watchdog.
257 * 16.01.95 -- 3.06.01 KANJI patch. doc/Makefile.in fixed.
258 * Install now calls doc/Makefile install.
259 * Don't use 'ds' too often, breaks MSkermit.

262 * Use \r (not \n) to join lines in pastebuf.
263 * bindkey can now remove sequences.
264 * InitTTY fixed for PLAIN. -- DISTRIBUTED
265 * 06.02.95 -- 3.05.66 DisplayLine() does now clipping to reduce coredump-
266 * frequency. Window size is adapted to the display that
267 * types input, to reduce multi-user confusion. Scrollback
268 * mode still may get the wrong size.
269 * 07.02.95 -- 3.05.67 WinRewrite() also needs to clip. Users without unix
270 * account, but with screen password allowed. Chacl
271 * allows password change, su prompts for user name too.
272 * 01.03.95 -- 3.05.68 Leaving a window may now cause a resize to match a
273 * remaining display. Simple ESC-CR fix in the vt100
274 * state machine.
275 * 26.03.95 -- 3.05.69 Markroutine() needs to resize the window to avoid
276 * coredumps, just like WinProcess() already does.
277 * More NEED_ flags added in comm.c to avoid coredumps.
278 * 04.04.95 -- 3.06.02 Simple ESC-CR fix in the vt100 state machine.
279 * Now compiles again with all extras disabled.
280 * Zombie resurrect added. defc1, defgr, defkanji
281 * added. Screen now replies to a secondary DA
282 * query. Some missing NEED_XXX added in comm.c.
283 * Better default tty permissions/group test.
284 * More AUX support, now compiles with POSIX.
285 * Function keycodes xtermified (F11, F12).
286 * Paste bug fixed (only worked with KANJI).
287 * Check bcopy before memcpy/memmove.
288 * FindSocket code much fixed & improved.
289 * 10.04.95 -- 3.05.70 Display_displays() now shows the users permissions on
290 * the currently displayed window, this is easier than a
291 * full featured lsacl, but also helps. chacl can now copy
292 * users, but we need to copy windows.
293 * 26.04.95 -- 3.05.71 Multi digit screen numbers in utmp. MakeWindow() now
294 * echoes what it does, just like RemakeWindow() when
295 * 'verbose on' (default off).
296 * `screen -ls myname/' will find own(!) non-multi sessions.
297 * Command line option -q improved and documented.
298 * 'debug off' also shuts attacher debugging off now.
299 * 03.05.95 -- 3.05.72 'connect' command bugfixed. colon prompt improved.
300 * open(O_NONBLOCK) does not work on 4.1.3, using O_NDELAY.
301 * There are writes to exp_wid2chan[-1], XXX I just added
302 * fillers to the mux structure, please debug this ASAP!
303 * WindowByName() prefers exact matches now. Esc forwarding
304 * from Frontend to Backend suppressed unless specified.
305 * 26.06.95 -- 3.05.73 Improving the combination of dflag and rflag: If both
306 * are set, a screen session is reattached, regardless
307 * if it was previously detached or attached elseewhere.
308 * "screen -D -RR" is thus most powerful: Give me my screen
309 * session here and now. No matter, if this means creating
310 * a new session (due to the second R without warning
311 * message), detching the session first (and due to the
312 * capitalised D logging out), or simply attaching to it.
313 * 13.07.95 -- 3.05.74 Markroutine learned new join mode: comma seperated.
314 * Can disable the detach feature from config.h.
315 * Configure.in now calls etc/toolcheck. Password is no
316 * longer a static array.
317 * 30.07.95 -- 3.05.75 Karl Heuer wants to install with a relative symlink.
318 * Command line option -k removed (try -t).
319 * 31.08.95 -- 3.06.03 Color support, digraph command, code
320 * cleanup (struct mchar/mline added).
321 * 03.09.95 -- 3.06.04 SetRendition display check. Solaris unblock
322 * SIGHUP. w_curchar->w_rend, lintified.
323 * Shadow-password code moved and rewritten
324 * (includes sun C2).
325 * 06.09.95 -- 3.05.76 Added support for braille displays (by Hadi Bargi Rangin
326 * and Bill Barry, {bargy,barryb}@dots.physics.orst.edu
327 * Added baud, cs8, istrip, ixon, ixoff options for plain
328 * tty windows. Untested.
329 * 09.09.95 -- 3.07.99 Merged 3.7.76 back into the main distribution but
330 * without network, blankwindow and dlist support.
331 * Global variable Password removed.
332 * Resize code completely rewritten.
333 * New commands: sorendition, (def)charset.
334 * strftime-like message generation.
335 * 26.09.95 -- 3.06.05 resize code completely rewritten.
336 * Very visible cursor added. vbell sequence
337 * \Eb added. _delay for terminfo libs added
338 * to make the padding work for the first time.
339 * New ProcessInput() makes "command command"
340 * work. '[def]escape ""' clears escape chars.
341 * Changed logdir command to logfile. It now uses
342 * MakeWinMsg() to create the filename.
343 * Updated the manuals.
344 * 03.10.95 -- 3.08.00 Merged 3.07.99 back into my 3.06.05.

346 * sysV68 configure test. Socket protocol got
347 * revision number. New command termcapinfo.
348 * Screenrcs, docs & configure.in updated
349 * 18.10.95 -- 3.08.01 Info shows parser state.
350 * Very visible cursor added. vbell sequence
351 * \Eb added. _delay for terminfo libs added
352 * to make the padding work for the first time.
353 * Braille code almost completely reworked.
354 * New ProcessInput() makes "command command"
355 * work. '[def]escape ""' clears escape chars.
356 * Command logdir -> logfile and uses MakeWinMsg.
357 * Updated the manuals. New mark command 'x'.
358 * stuff has new "-k" parameter.
359 * 28.10.95 -- 3.06.06 Added new 'XC' capability to provide
