...because the "diff --color-words" for this version of the patch makes
it clear you only have to rerun

sed -e 's/make_absolute_path/real_path/g'

etc. on the affected files to resolve this "merge-compile conflict".

Just pointing it out for those who wonder why I pestered Carlos to bring
the patch into this form, and why Junio started to like failed builds.
Also, I need to make-up for making Junio explain my recent RFD :)

Cheers,
