No, it doesn't help

Not sure how to test this? I've did ls github/<tab>, and there was no change

I've committed the two changes but it didn't help.

It is like so. I've added a print to the end of _main_complete, and
the output was:

“... more entries ... (-default-)*.o=2;37 (-default-)*~=2;37
(-default-)*.zsh_history=2;37 (-default-)*.zcompdump=2;37
(-default-)*.bash_history=2;37 (-default-)*.viminfo=2;37 (-default-)”
(-default-)=(#b)(*)/(*)==1;35=1;33

This pointed to the fact – why the quotes around the first entry and
not around the second? They're the Unicode quotes... fixing them helps
– I can see correct highlighting. But should the quotes be disrupting
the completion in such a way that a following, correct entry doesn't
work? And – the first entry was working OK for the things like ls
<tab>.

I've tried two definitions: https://github.com/trapd00r/LS_COLORS and
https://github.com/zpm-zsh/dircolors-material and two had the same
problem (before noticing the Unicode quotes), so that's rather not it.
