livecheck.distname is not properly escaped in livecheck.regex

[ryandesign@…]

livecheck.distname is not being properly escaped before being put into livecheck.regex. I noticed this problem while trying to update the livecheck for osxvnc, setting livecheck.distname Vine Server(OSXvnc). With livecheck.check sourceforge, this results in the regex "<title>Vine Server(OSXvnc) (.*) released.*</title>" which is incorrect. The regex I wanted was "<title>Vine Server\(OSXvnc\) (.*) released.*</title>". There must be a Tcl function we can use which would properly escape a string for use in a regular expression, like preg_quote() in php.

Looking through all ports, I see that fixing this will break the livecheck in the portfiles for fusefs and spotlightfs, which currently assume this bug exists.

Replying to ryandesign@macports.org:

Doesn't look that way, but then again it isn't impossible to just add one either.

Fixed in r34667.

Now really fixed in r34693, the previous commit broke other regexes.
