 `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
 [http://www.php.net/preg_quote 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.
