Dunno if it's "blocking" but it'd be nice to resolve those "exec" with
variable assignments that Jun T. pointed out.

I have the following un-pushed changes (some of which have been posted
in previous articles, some not):

 remove _message from _mkdir
 unquote history words when command line has a quote
 no files to add in compaudit
 compsys.yo tweak "will" -> "will be"
 local TZ in strftime
 quote/quotebreak remove useless cast
 doc vindex pid
 allow clobber of zero-sized files
 maybe-helpful change free() to zfree() in two places
 add backslash to alias expansion matching in _expand
 test for breadth-first glob with (Y1)
