Smart one! This is nice, but this time I got other issues:

$ rpm --*er[tab]

without glob_complete, this method of finding options for SOME commands
stops working. What's the difference between ps --* and ls --* that the
latter still works?


And back to my example:

$ touch 2021.12.29-14:41:02.xz 2021.12.29-19:41:02.xz 2021.12.30-03:41:03.xz 2021.12.30-14:41:04.xz 2021.12.30-19:41:02.xz 2021.12.31-03:41:02.xz 2021.12.31-14:41:04.xz 2021.12.31-19:41:03.xz
$ ls *04[tab]
- this one is much nicer than my version, goes directly to:
$ ls 2021.12.3-14:41:04.xz		(note the suffix)
with cursor __^__ placed here, on dash. However, unless I move cursor
left+right manually, pressing tab second time moves cursor to the end
with uncompletable line...

And following one fails miserably...
$ ls *z[tab]
$ ls 2021.12.-

See the dash at the end? From now on, no completion... This problem is
solved by alternating order to _expand _complete _match.

Apparently _complete _match parts doesn't work well here in that order,
however _match _complete (only!) works just like my solution without
compstate[old_list]=keep, therefore one of the following seems to work fine:

zstyle ':completion:*' completer	 _match _oldlist _complete
zstyle ':completion:*' completer _expand _match _oldlist _complete _prefix

But no suffix added, just like in my version.
Moreover, in this order there's no need to unsetopt glob_complete.

Am I missing something?


There is still one issue with coloring completions, that works fine with
my approach, but seems to be stuck on _oldlist:

highlights='${PREFIX:+=(*/|)(#bi)($PREFIX|$PREFIX:t)(?)(*(${LASTSEARCH})*)#*==1;32=1;31==1;32}':${(s.:.)LS_COLORS}
zstyle -e ':completion:*:*' list-colors 'reply=( "'$highlights'" "ma=44;1;33")'

With _oldlist in action the colors are not updated after prepending the
unambiguous part.
