Correct.

True. But we do not do a very good job preventing this to happen.
$ git -c alias.loop='loop foo' loop foo
fatal: recursive alias: loop
$ git -c alias.loop='!git loop foo' alias foo ;# does not come back
^C
To be honest, I do not offhand see a foolproof way to "fix" the
latter.

It is true that it would break common expectations for script
writers (to help other Git users) and those who help other Git users
at their keyboards if we allowed to alias the basic command away and
to change its behaviour radically. But with so many configuration
variable to alter behaviour for Porcelain commands, I am not sure
how much it is helping the latter helpers these days. For the
former helpers, those who write their scripts with Porcelain
commands are beyond salvation X-<.
Thanks.
