Comment:
Either my patch-fu is rusty or I made some xbps-newbie mistake... I can apply the patch by hand to 1.18 with "patch -p1 < $patch", but when I try under xbps-src it doesn't apply.
The package also needs copy-file.[ch] from gnulib, which were imported in a previous commit, but until I don't know why patching fails... can you look at it?
The command I ran to test if the program builds was "./xbps-src pkg recutils"; srcpkgs/recutils/patches/exdev.patch is simply downloaded from upstream, and the failed attempt is below
