I'm experiencing an issue when using aliases for commands that open the pager.
When I press Ctrl-c from the pager, it exits. This does not happen when I
don't use an alias and did not happen before. It causes problems because
Ctrl-c is also used for other things, such as canceling a search that hasn't
completed.
To reproduce, create e.g. the alias `l = log` and run `git l`. Then press
Ctrl-c. The expected behavior is that nothing happens. The actual behavior is
that the pager exits.
I bisected the repo, and found that the commit 86d26f240 [0] introduced the
issue.
