URL regular expression is incorrect

[Emmanuel Blot]

The regular expression used to expand wiki links is incorrect

It is too greedy with the URL characters, which leads to include non-URL information into the URL group.

For example, in the following graphviz data extract:

my_node [URL="http://server/trac/project/changeset/164",tooltip="author"]

the RE engine considers that ",tooltip="author is part of the URL definition, which is incorrect.
The URL ends up corrupted, double-quote are escaped (sanitized), and the tooltip is destroyed.
