Not so much surprising, no, but I hadn't expected it to fail altogether on entries that just end after one line of text just because they lack a newline character - they are a one line text after all, so I assumed that the diff would produce a "replace this old line with the new one" type of instruction instead of producing something that patch doesn't seem to be able to process at all.

Kind regards
