I observe exactly the consequence of this behaviour. First, the error
is emitted and then the pager kicks in to list the branches.

I just thought we wouldn't want to surprise/confuse users who try to
use "git branch -l" with the warning message about "create reflog"
along-side the list of branches. That would just add to the confusion.
So, I thought we should error out when users do "git branch -l"
instead. Something like the following should help us prevent "git
branch -l" from listing branch names and might also prevent the
confusion.
