At first I thought this was a(nother) problem with _path_files but it
appears instead to be pretty plainly this in _rm:
case $state in
(file)
declare -a ignored
ignored=(${line//(#m)[\[\]()\\*?#<>~\^]/\\$MATCH})
_files -F ignored && ret=0
;;
esac
A _complete_debug trace shows:
+_rm:33> case file (file)
+_rm:35> declare -a ignored
+_rm:36> ignored=( foo )
+_rm:37> _files -F ignored
The most recent change was:
2009-08-17 Peter Stephenson <p.w.stephenson@ntlworld.com>
* 27219: Completion/Unix/Type/_files: "_files -F <array>" wasn't
correctly handled, which broke duplicate filtering in _rm.
(BTW "wasn't" has a UTF-8 apostrophe in the actual ChangeLog file.)
So _rm is attempting to filter duplicates out of the completion list,
but ends up filtering out unambiguous prefixes as well. Fixing one
bug exposed a different one.
The easy fix of swapping in
{ _files -F ignored || _files }
solves the foo{1,2,3} variant but not the foo{,-bar} variant because
the presence of foo-bar allows _files -F to succeed even though it
skips foo. There may not be a way to satisfy all constraints here.
