I consider this to be conclusive evidence that your testing was erroneous so that your only explicit criticism of the original patch should be ignored. You apparently have not tested with a user name at the end of the file without a trailing newline character as you claimed. I still think that user names must each start at the beginning of a line and must be followed immediately by a newline character -- all other lines are ignored. (They probably also must be in some user account config file(s) but that should go without saying.) As for the state of the PR, I'm still not aware of anything particularly wrong with the original patch and hope that committers will consider that patch. I'll consider modifying it in response to criticisms of it and suggestions for its improvement, of course. In case you're still interested, that "0a" just after "73" in your "hd" output is the "newline" character at issue. Your file ends with a newline character (so your user name is used); mine doesn't (so my user name is ignored). As you can see, newline at the end of a file is a troublesome thing. Some programs consider newline to be a part of a line and insist on ending the file with a line with a newline. My editor (XEmacs) will not move the cursor below the "jojo" line of my file, but will move it below the "marcs" line of yours and will increment the line count in doing so. The "wc" program would show one more line in yours than mine. The "diff" program seems to see a blank line in both files and shows two blank lines as being different. Your shell (and my pdksh) seem to ignore the empty line so it doesn't show as a blank line.

He's the kind of guy that has likely also said the exact opposite because it's just as profound or cute or whatever he's going for at the time. (In fact, "kind" and "right" are more important than the other in different circumstances.) He's made a career out of complaining about what people do wrong on a show that does the same and they all have found it important to be unkind and, worse, unfair.
