From: Trygve Aaberge <trygveaa@xxxxxxxxx>
When you hit ^C all the processes in the tree receives it. When a git
command uses a pager, git ignores this and waits until the pager quits.
However, when using an alias there is an additional process in the tree
which didn't ignore the signal. That caused it to exit which in turn
caused the pager to exit. This fixes that for aliases to builtins.
This was originally fixed in 46df6906f3 (see that for a more in
explanation), but broke by a regression in b914084007.
