That's really cool :) And I find it useful (and already applied it to
my tree). For me, it works like a simple reminder about what I was
about to do. Helps when working on many things at the same time
(typical typo: mrge. And your patch shows it as the first hit).
BTW, you probably want to restrict the number of lines output.
For instance, "git ma" (am, printed correctly in the first line)
lists around 30 commands, which scrolls clear a 25 line terminal
and is a lot of output anyway. I tried it with at most 5 hints:
diff --git a/help.c b/help.c
index ac29225..765eed8 100644
