Add --verbose|-v to test-chmtime
This allows us replace perl when getting the mtime of a file because
of time zone conversions, though at the moment only one platform which
does this has been identified: Cygwin when used with ActiveState Perl
(as usual).
The output format is:
<mtime1> TAB <filename1> <LF>
<mtime2> TAB <filename2> <LF>
...
which, if only mtime is needed can be parsed with cut(1):
test-chmtime -v +0 filename1 | cut -f 1
Also, the change adds a description of programs features, with examples.
