But then again, any programmer or developer of some kind... and indeed
anyone who should be using Mercurial would know not to use that piece of
crap that is notepad :-p. They can at least use some free light-weight
alternatives like notepad2 or similar, which understands \n.

Personally, I don't think .txt is important either, as I would always
just invoke my editor on the file from a shell. Seems a bit weird to
navigate into a 'secret' folder like .hg in a file explorer anyway.
