[PATCH RFC] show-branch: use pager

This is for consistency with other porcelain commands such as 'log'.

The rationale for this patch I hope is consicely explained in the commit
message. I was rather surprised it didn't use a pager as I've gotten used to it
for most commands.

I marked this as an RFC because of Jeff King's comments in
daa0c3d97 where I got the impression this this might not be a good idea.
However I haven't found any bugs and all the tests pass. It is more a huble
suggestion than anything but I thought I might as well send it as a patch.

setup_pager() is already pulled in via cache.h so there was no need to add any
#include directive. I suppose this is as close to a one-liner as it gets :)

Best regards,
Øsse
