So, one of the things which fell out of this thread is that "hg log"
doesn't pick up everything one might want it to pick up, and inquired
about it at the hg list.
I got a very nice explanation about how hg works in this regard from
Matt himself. The thread can be found at
http://selenic.com/pipermail/mercurial/2007-May/013230.html
I hacked up a script "hg_traverse" which does pick up what happened here
- if you call it within the dev repo as "hg_traverse lrm/lrmd/lrmd.c tip
500", it'll follow up to 500 changesets from the tip and filter out any
changes to lrmd.c. (I attached it here for convenience.)
It's bloody slow, but it works. Maybe someone will implement it in
python proper for hg.
Regards,
Lars
