If you don't mind upgrading, you can do such things with the new bindable
completion widgets in 3.1.9 (maybe 3.1.6, but that's irrelevant if you're
still on 3.1.5).  Assuming the file is unique, you can use
e.g. _most_recent_file (usually bound to ^xm), which would normally put a
`*' on the end and find the most recently modified matching file --- that
ought to be enough for this purpose.

The following function is a trivial modification of that to add all
matching files as possible completions (_glob_expand_and_complete).
Sven probably has a better way of doing it.


#compdef -k complete-word \C-xG

local file tilde etilde
if [[ $PREFIX = \~*/* ]]; then
  tilde=${PREFIX%%/*}
  etilde=${~tilde}
  file=($~PREFIX*$~SUFFIX)
  file=(${file/#$etilde/$tilde})
else
  file=($~PREFIX*$~SUFFIX)
fi
(( $#file )) && compadd -U -i "$IPREFIX" -I "$ISUFFIX" -f -Q $file
