Add brew tab, a new command to edit tab information, as previously discussed in #17125 (comment). Currently, this supports marking or unmarking formulae as installed on request.

Sample usage:

$ brew tab --installed-on-request curl
==> curl is now marked as installed on request.
$ brew autoremove --dry-run
[no output]
$ brew tab --no-installed-on-request curl
==> curl is now marked as not installed on request.
$ brew autoremove --dry-run
==> Would autoremove 2 unneeded formulae:
curl
rtmpdump

Thanks for this! Looks good from a brief look but hold off merging until after next stable release so I can do a proper review tomorrow. Thanks again ❤️

Looks good so far, thanks @ZhongRuoyu!

I'm not sure this is ready after seeing other comments.

Just to note: brew install <already-installed-formula> already does the behaviour of brew mark --installed-on-request <formula> - it's just the reverse that's currently not possible.

Feels a lot to type though - might be worth shortening to auto/manual, --requested or something else?

For consistency I chose to go with the flags already present in brew leaves:

$ brew leaves --help
Usage: brew leaves [--installed-on-request] [--installed-as-dependency]

List installed formulae that are not dependencies of another installed formula
or cask.

  -r, --installed-on-request       Only list leaves that were manually
                                   installed.
  -p, --installed-as-dependency    Only list leaves that were installed as
                                   dependencies.

But perhaps we can add short flags. Need to come up with a short flag for the negation (e.g., --no-installed-on-request), though.

I feel given it's less "safe" (i.e. can trigger autoremove): we probably don't need a short flag for this.

Looks great, thanks again @ZhongRuoyu!
