in the code snippets perl syntax highlighter, this regexp:
$string =~ s/^\s+//;
the first 's' after the '=~' operator is correctly linked to the perldoc page concerning the 's' function, the second 's' however is also linked to the same page, which is not correct since it is the meta character for a white space.
Also, the links should probably really go to:
perldoc.com never seems to be online anymore.
This is of course nothing very important, just thought I would bring it to your attention.
