It's CR.

It's probably best not to use "\n" and "\r" because "\n" is ambiguous.
To a Mac programmer, for instance, it means a CR, and to a Windows
programmer it means CRLF - maybe not in C, but certainly in Perl.
Stick to numeric values.

Agreed - it's better to be explicit.
Another thought: don't assume a file is binary just because it doesn't
have any CR or LF characters! It might use the Unicode line separator
LS (2028) or paragraph separator PS (2029), Or even EBCDIC NEL,
which is in Unicode as 0085. This is all discussed at:
<http://www.unicode.org/unicode/reports/tr13/>
May I suggest LS as the repository's native newline character?
Peter.
