Add the --succinct flag to type

[hivehand]

Description

Add a new flag, -s/--succinct, to the type function: when used, it suppresses the expansion of function definitions normally performed by type <name> and type -a <name>.

Fixes issue #6402

TODOs:

• Changes to fish usage are reflected in user documentation/manpages.
• Tests have been added for regressions fixed
• User-visible changes noted in CHANGELOG.md

This looks entirely reasonable, but I'd rename the flag to "--short".

Thanks! I've changed "--succinct" to "--short". I've also added what I should have put there in the first place: functionality which, if the path to the function is known, prints it in parentheses, e.g.:

$ type -sa umask
umask is a function (defined in /usr/local/Cellar/fish/3.0.2/share/fish/functions/umask.fish)
umask is /usr/bin/umask

If the path isn't known, everything inside the parentheses is omitted.

Nice work, merged, thanks!
