Re: [PATCH] Show number of commits being rebased interactively

[Junio C Hamano <gitster@pobox.com>]

I see nobody commented on this, which probably fell into cracks.
Even though I am personally not very interested, I obviously am not
the only user of Git, and there may be others who are interested in
a change like this.

These lines above "---" will become the only log message text, which
is probably not what you intended.  Use "-- >8 --" marker instead
(that is a perforation line with a pair of scissors on it)?

Does this count the number of commits?  I suspect it at least needs
to filter "x|exec" out.
