Strange, I tried with:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
And with my local trees, on:
[acme@zoo linux]$ cat /etc/fedora-release
Fedora release 20 (Heisenbug)
Further details down, but in all those cases pressing 'a' works for me
