When the WPMU site name, as defined in wpmu-options.php, has an apostrophe in it - Matt's Great Network for example, the apostrophe is escaped with a forward slash, creating this result - Matt\'s Great Network.
However many times I visit that page, correct the name, and save, it still keeps staying there.
This appears wherever the WPMU site name is displayed, in the footer of the default theme for example.
Any fix for this? I didn't find one in trac but maybe I didn't look properly.
