Thinking more about this, there is one non-trivial issue: concatenation. It's common for code in Emacs to take a regexp, assume it's a string, and do something like (concat "\\(" some-regexp-var "\\|" some-other-regexp-var "\\)").
Solution 1 could be tweaked to wrap the whole regexp: "\\(?pcre:…[pcre regexp here]…\\)", and so could solution 3 (a text property spanning the whole length of the string), but solution 2 won't work well here.
Not to mention the fact that if the regexps are matched by different engines, we now have to make these work together :/
Clément.
