Hmm, is looking only for pick the right thing?
Stepping back a bit, I have to wonder what we want to count. The number of commits after the rebase is done, or the number of commits in the input of the rebase operation?
The generation loop that reads from rev-list may add only "pick", but then rearrange_squash will munge some into squash and fixup. We may even have some more automated editing of the insn sheet in the future, just like add_exec_commands were added, so I think it is more prudent to go from the full list of possible insn sheet commands (that is, pick, reword, edit, squash, fixup and exec) and count them, not just relying on "we know the rev-list loop happens to add only pick commands".

Hmph, interesting. Then perhaps not filtering at all and instead labelling this new piece of information not "commit(s)" a better solution? You are counting the number of instructions in the insn sheet, so perhaps something like "($count todo items(s))" or something?

That is not a scissors line, I suspect.
I didn't try running "git am" on this message, though. Did you?

Just a scripting tip. When a line ends with a vertical bar (pipe), the shell parser knows that you haven't finished speaking, so there is no need to have "\" there.
