This also looks good to me.
unrelated:
Patch 2 was very easy to review using "log -p -w --color-moved",
this one however was not. This is because -w caused the diff machinery
to generate a completely different diff. (Not showing the new function
completely but some weird function header trickery. The white space
mangled output is below; most of it was colored "moved")
I had to have -w as otherwise --color-moved would not work,
so maybe we want to have an option to ignore white space for the
sake of move detection only, not affecting the diff in general;
maybe '--ignore-white-space-in-move-detection'?
I think once this option is given, all we have to do is pay attention to
this option in diff.c#moved_entry_cmp/next_byte, which is best built
on top of Peffs recent fixes origin/jk/diff-color-moved-fix.
Would that be of interest for people?
Thanks,
Stefan
