\r and \fn regex are wrong

[moi15moi]

\r and \fn can match to string when it should not.

Example:
The \r will match with the r of the tag \frz
{\frz0\alpha&H00&\fn123marker\blur0.5\fscx37\fscy34\pos(963.28,788.5)\c&H071B1E&\3c&H071B1E&}tooth{\clip(m 962 761 l 961 773 961 782 962 793 997 790 997 765)}
