How to properly solve "git-gui: command not found" on Arch Linux?

Question

The Arch Linux git package installs git-gui under /usr/lib/git-core/.

This means git-gui cannot be launched directly from the terminal without specifying the full path:

$ git-gui
bash: git-gui: command not found
$ which git-gui
which: no git-gui in (/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)

I'm at a doublt as to what would be the way to properly solve this.

1. Add /usr/lib/git-core/ to system-wide $PATH?

2. Create symlink to /usr/lib/git-core/git-gui under /usr/local/bin?

3. Report a bug in the Arch Linux package? Or upstream?

4. Do nothing - this is not a bug?

Thank you.

This is expected behaviour. All git sub-commands are installed to there — you will also find git-commit there, though probably as a link to the main binary for efficiency these days — and the main git command knows where to find them.

Any executable git-X there becomes available as git X automatically, and that's the expected way to access them rather than by path or the hyphenated name. git gui is the normal way to access the git-gui executable, and is also what man git-gui will suggest.
