git-bisect uses show-branch for logging during the bisect process. If the user
sets an interactive pager for show-branch, this makes bisect hang (wait for
user input) unexpectedly - so we disable pager with -P.

It's possible that the user would set a pager for git-checkout as well, but an
interactive pager there would break many more scripts.
