I'm OK to drop this patch. The reason I've submitted it is: It is now muscle-memory for me to invoke my NEdit macro for stripping space-at-EOL. Git considers space-at-EOL a source code wart, and some text editors even auto-strip space-at-EOL, so I've grown to just prevent git from complaining, and manually but routinely strip space-at-EOL before saving the file I'm editing. Now, when the file I'm editing has preexistent space-at-EOL, that turns into a second-level annoyance: "git diff" and friends think I intend to change the *old* source code like that as well. To get rid of that misunderstanding, I actually tend to collect the space-at-EOL removals for *old* code into separate patches (with "git add -p"), post and merge them, and then focus on the real stuff subsequently. The point being that unjustified space-at-EOL should not / would not be reintroduced ever after. You are right that we have space-at-EOL in very many POD files (I had noticed :) per the above); I figured I'd test the waters with this patch first! :) Thanks Laszlo _______________________________________________ Libguestfs mailing list Libguestfs@redhat.com https://listman.redhat.com/mailman/listinfo/libguestfs
