Hm. I considered the sentence to be in imperative mood already. I guess I
don't fully understand what imperative mood is. Will fix.

You are right, I didn't run get_maintainer.pl this time. I never got it
integrated properly into my workflow. How do you use it? Is it part of
'git send-email' hooks or do you do it manually somehow.

I don't feel I can trust the script to do The Right Thing™ all the time
to put into my hooks. I expect it to blow up on tree-wide patches for
instance.

As result I only run it occasionally, when I remember to which is
suboptimal.

Any tips?
