bug#19113: Generate a ChangeLog file from commit logs

We could add that capability to gitlog-to-changelog, if needed.  It shouldn't be 
hard.  I'm hoping it's not needed that much.

That's correct.  It's mainly intended to correct serious errors, e.g., 
misattribution.  To help give a feel for it, of the 3329 commits to GNU 
coreutils master since it began generating ChangeLogs automatically, only 7 have 
been corrected in coreutils' build-aux/git-log-fix file.
