/**
* hildon_helper_smart_match:
* @haystack: a string where to find a match
* @needle: what to find
*
* Searches for the first occurence of @needle in @haystack. The search
* is performed only in the first alphanumeric character after a
* sequence of non-alphanumeric ones. This allows smart matching of words
* inside more complex strings.
*
* If @haystack itself doesn't start with an alphanumeric character,
* then the search is equivalent to strcasecmp().
*
* To make the best of this method, it is recommended that both the needle
* and the haystack are already normalized as ASCII strings. For this, you
* should call hildon_helper_normalize_string() on both strings.
*
* Returns: a pointer to the first occurence of @needle in @haystack or %NULL
* if not found
