Thanks. The subject caught my attention. The patches look good and
fast-import is usually maintained by me applying them and Junio pulling
from my fast-import tree. I'm doing that now.
BTW, I haven't thanked you for doing this cleanup work. It really
is appreciated. The code is definately more readable in the end.
Thanks.

The Linux kernel folks were talking about this not too long ago
and the discussion spilled onto the git list when someone CC'd it
in the middle of the thread. If I recall correctly it ended off with
this is probably something that a build script should be doing, not
something Git should do natively, as the data is readily available
from tools like git-log.
Indeed in this case if you do:
$ git log --pretty=format:%an --since=6.months.ago -- fast-import.c \
| sort | uniq -c | sort -nr
14 Shawn O. Pearce
3 Pierre Habouzit
3 Junio C Hamano
2 Simon Hausmann
2 Alex Riesen
1 Theodore Ts'o
1 Sven Verdoolaege
1 Sami Farin
1 Nicolas Pitre
1 Luiz Fernando N. Capitulino
1 Dana L. How
So you'd probably want to CC me on stuff in that file. On the other hand
looking at something else that's much more important to Git:
$ git log --pretty=format:%an --since=6.months.ago -- builtin-pack-objects.c \
| sort | uniq -c | sort -nr
38 Nicolas Pitre
12 Junio C Hamano
4 Dana L. How
3 Martin Koegler
3 Linus Torvalds
3 Brian Downing
2 Theodore Ts'o
2 Dana How
1 Luiz Fernando N. Capitulino
1 Geert Bosch
1 Alex Riesen
I don't think anyone would argue that CC'ing Nico and Junio on all
sizeable pack-objects changes would be prudent. Dana too actually
as he has been active in here recently. Meanwhile I don't make
the 6 month cut. ;-)
The other alternative that men with real computing horsepower at
their disposal can ask is through git-blame:
$ git blame -C -C -w --porcelain builtin-pack-objects.c | grep 'author ' \
| sort | uniq -c | sort -nr
52 author Nicolas Pitre
39 author Junio C Hamano
22 author Linus Torvalds
6 author Shawn O. Pearce
6 author Dana L. How
3 author Martin Koegler
...
Again Nico scores very high (52 commits surviving in current `next`)
but so does Junio and Linus. The output of git-blame may actually
be a better indicator of who Junio likes to CC when changes are
made in this module.
Doing something like this automatically based on the filepaths shown
by `git diff --name-only $cmit^ $cmt` could be expensive in terms
of CPU time, and might offer little gain for an old hand who knows
where the maintainer boundaries tend to be, but it does really help
someone who is newer to the project and might not know who is the
best person to talk to.
