I didn't think of that, but certainly did edit the output of format-patch before myself. I suspect the effort to update the header would be bearable, as it doesn't need to be exactly right and is only needs to shield the part that looks like a patch. We could not actually use "Lines" as the name for the header, by the way, as it's already defined to be the number of lines in the whole email. Mailinfo would ignored any patches sent using a MUA that adds such headers. Anyway, adding a header would not cover the case where someone adds a diff manually (and without indentation). > As nobody in the discussion seem to care any e-mail source other > than format-patch, we may probably be able to teach mailinfo that > > * the first line that > - begins with "diff " or "Index", or > - is "---" (and nothing else on the line) > signals that the line no longer is part of the log > > * but if it finds a line that begins with "diff --git" (or > optionally just "diff "), do not blindly assume that is the end > of the log, and instead try to find the first "---" line.

It will probably be tricky to implement, though, as mailinfo currently goes through the input line by line and has no easy way to look ahead. René
