Support fzf syntax in pickers

[rcorre]

Could we add support for fzf syntax in pickers?

Token	Match type	Description
sbtrkt	fuzzy-match	Items that match sbtrkt
'wild	exact-match (quoted)	Items that include wild
^music	prefix-exact-match	Items that start with music
.mp3$	suffix-exact-match	Items that end with .mp3
!fire	inverse-exact-match	Items that do not include fire
!^music	inverse-prefix-exact-match	Items that do not start with music
!.mp3$	inverse-suffix-exact-match	Items that do not end with .mp3

Right now, the picker appears to interpret these characters literally.
I mainly find myself missing "inverse" and "exact".

Already done in #5114

That's great, thanks! Sorry, I did try a number of searches but didn't see it.
