VERY quick and dirty regex to hunt for string literals that may need to be localised

Explanation:

The conceptual template is:

(?<!PREFIXES_I_DONT_CARE_ABOUT)\s*(?!STRINGS_DONT_CARE_ABOUT)@".+"

(?<!foo|bar) is negative look-behind for "foo or bar". It eliminates any matches preceded by foo or bar.
(?!foo|bar) is negative look-ahead for "foo or bar". It eliminates any matches followed by foo or bar.
The basic idea is to find string literals, eliminating the common cases of @"%@" and @"%d" and eliminating typical Cocoa method and function calls that indicate a non-user-visible string.

With a real-life project, this reduced the number of hits from ~1500 to ~400.

I used BBEdit to search the whole source tree with a filter for Cocoa files (extensions m, mm, h and hh).
