Their names are not perfect, so let's keep them as internal functions,
until we figure out how/if we want to expose this.
This reverts 0445126c2 (Undunder __fish_is_nth_token, 2021-06-29) (but I
did it without "git revert").
Closes#8008
We keep __fish_is_nth_token for compatibility and edit the
implementations of __fish_is_nth_token, __fish_is_first_token and
__fish_is_token_n to use fish_is_nth_token
A minor follow-up to #6866 (e658a88ab0).
These file types should be properly handled by other unzip flavors too,
regardless of Debian's/non-Linux Unixes' idiosyncrasies.
I've been dealing with these a lot recently (android dev...), and it's
pretty annoying that unzip completions don't recognize them (They're
just zip files with a weird file extension).
macOS and (AFAICT) most Linux distributions ship with the Info-ZIP
version of unzip, which has the `unzip -h` flag; but other
implementations of unzip do not necessarily have it (i.e. FreeBSD).
`unzip` under FreeBSD does not support `unzip -h`. Under both Linux and
FreeBSD, `unzip -v` presents the list of options, though. Using this
instead of `unzip -h` to detect the Debian-patched version of the
Info-ZIP unzip program.
