Re: Bug report; git tab-completion on macOS within paths containing unicode characters

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

This used to work in 5.7.1 (default shell on Catalina).  Then this
change was made:

-  local pref=$gitcdup$gitprefix$PREFIX
+  local pref=${(Q)${~PREFIX}}
+  [[ $pref[1] == '/' ]] || pref=$gittoplevel$gitprefix$pref

Unquoting the prefix with (Q) seems to have broken it.  That came from
workers/45313 ("revised version of workers/41523").  Daniel?

A different fix to try:
