[PATCH] Allow tab in rules

Hi all,

namedev_parse is a bit overzealous when in comes to handling backspaces;
it always eats up backspaces regardless of anything beyond that.
This means it is impossible to enter '\t' in a rule.
Quite a bit of fun when you're trying to write regexps.

The attached patch fixes that, so now you should be able to use
'\t' and '\\' within the rules file.

Cheers,

Hannes
