Hi,

I'm a new maintainer of git in RHEL. We have encountered a bug where
merge-base is missing in bash completion. [1]

First I applied a patch[2], that should fix this problem, into
git-1.8.3.1 we are using in RHEL 7.7 and I discovered that completion
is still missing.

Then I tried to reproduce this bug in the newest version of git and
completion is still missing.

Hi Ondřej,

The `merge-base` command is not considered a user-facing command:
https://github.com/git/git/blob/v2.25.0/command-list.txt#L120
(the "plumbing" in "plumbinginterrogators" means that this is supposed to
be a low-level command, to be used in scripts, but not so much
interactively).

Therefore I think that it is intentional that this command does not
tab-complete: to declutter the list when typing git<TAB><TAB>.

Ciao,
Johannes
