Tweak to fix for #4233 -- only accept word chars in types

With the title carrying semantic information it may contain arbitrary chars;
when parsing a ref we only want word chars in the type (up to the first open
square bracket) and everything else, enclosed in "[" / "]" to the end of the
string, is the title.
