We discovered a bug that results in malformed HTML due to the text/html filter (mhtxthtml.pl) not handling certain URLs properly.  The filter incorrectly strips URLs that are in the query parameters of other URLs, such as with Outlook Safelinks URL rewriting.

The regex wrongly identifies a 'url' get parameter as an HTML attribute and then double quotes are inserted around it.

The only workaround I currently have is a hack, changing the line ~378 to read:

/join("",$1,'',&resolve_cid($onlycid, $2, $atdir),'')

Rather than:

/join("",$1,'"',&resolve_cid($onlycid, $2, $atdir),'"')

(ie, remove the double quotes)

However, there is probably a better way of fixing this.
