common substring mixes - and _

• zsh-autocomplete version: 99f0b2a
• Zsh version: /usr/local/bin/zsh zsh-5.8-0-g77d203f
• Framework: zim
• Plugin manager: none
• Operating system: darwin19.6.0

when there are choices that differ only by - vs _, common substring is incorrectly calculated.

What I expect:

if I have directories foo-bar and foo_bar, I expect to be able to choose any of them using tab

What I get:

When I press tab it completes to foo-bar, so I can't choose foo_bar at all using completion.

REVISION: 99f0b2ad9bdaa8a94ed8edf489d0738d2303fd21
% mkdir foo-bar
% mkdir foo_bar
% cd foo
directory
foo-bar/  foo_bar/
common substring: foo-bar

# after pressing tab:
% cd foo-bar/
No matching directory, ancestor directory, corrections or history word found.

@vitaly I didn't change the common substring for your test case, because that's handled by zsh's internals and out of my control. But now, after you insert it, the other choices should still be visible and you should be able to complete them.

It worked, thanks!
