patching them, because git won't see the changes to them, and the build
process will overwrite them. Patch the originals instead. Most
utilities (like perldoc) are in this category, i.e. patch
-utils/perldoc.PL rather than utils/perldoc. Similarly, don't create
+F<utils/perldoc.PL> rather than F<utils/perldoc>. Similarly, don't create
patches for files under $src_root/ext from their copies found in
$install_root/lib. If you are unsure about the proper location of a
file that may have gotten copied while building the source
