topgit-0.17

TopGit-0.17

A polish and bug fix release.  Notably tg summary, tg info, tg update and
anything else that needs to traverse the entire dependency graph should
work much faster now when a large .topdeps dependency graph is involved.

Other niceties like optional remote branch name for tg create -r (assumes
its the same as the local name in that case), tg patch can now pass along
arbitrary options to git diff-tree in order to better inspect the potential
patch.  Also the temporary directory used in .git should always be removed
now, tg export --collapse creates unique committer timestamps on the commits
it synthesizes so any git rebase run on the result has a stable ordering
with respect to the TopGit .topdeps dependency tree and finally tg create
preloads a suggested commit message.

The tg summary command also got some love and --deps can now work on a
single branch, using --rdeps now changes the default from all branches to
the current branch and lastly one or more branches can be excluded from
tg summary's output.

Kyle J. McKay (17):
      tg.sh: change incorrect 'continue' into correct 'return'
      tg.sh: speed up recurse_deps_internal
      tg-checkout.sh: avoid trap and put temp files in $tg_tmp_dir
      tg.sh: make sure temporary directory is removed on signal
      tg-create: suggest a commit message
      tg-export.sh: make synthesized commits have unique timestamps
      tg-summary.sh: default to HEAD for --rdeps but allow --all
      tg-summary.sh: support --exclude option
      tg-create.sh: make remote branch name optional
      README: correct hint for producing conflict-free patch sets
      README: encourage use of git rerere
      tg-patch.sh: allow git diff-tree options to be passed through
      tg-export.sh: call rerere again after shell exit

      scripts: use more portable export
      style: remove C-like ';' statement terminators
