While I was thinking about potential issues before queuing this, I
realized that I forgot to mention one thing.
The name.
"filedirstat" is simply too long to type, and it has a certain "Huh?"
factor --- is it about file, or is it about directory?
This option essentially is just the dirstat but with different logic to
compute how big the damage is. Conceptually, the original one gives one
"damage point" to each added or deleted line.
$ git show --dirstat=<one-point-per-line>
and yours awards one point to each file, whatever the size of the damage
is.
$ git show --dirstat=<one-point-per-file>
I cannot come up with a short-and-sweet name for one-point-per-X offhand,
but expressing this variant as an option to --dirstat will leave the door
open for other people to come up with different system to award damage
points. Perhaps
$ git show --dirstat=exclude-typofixes
might even be not just interesting but useful ;-)
Again, I mention this not because I want to reject the patch, but because
I hope other people with better UI taste may come up with an alternative
before I finish handling other patches.
