Expanded from two elements (list of locations, extensions) to three. The first and new one is the filespec, which can have or not a path. Further, a path may be relative or absolute.
Changed "extension path" to "additional path" for application-defined paths. "Extension path" (which btw doesn't occur anywhere else in rexxref) is misleading and can be confused with the discussion about file extensions below.
Changed "extension types" to "extensions".
Added several examples.
Added a note for the (admittedly rare) case where one of the supplied paths (e.g, in REXX_PATH) is itself relative and therefore a double prepending is needed (e.g. current directory + REXX_PATH element + relative path supplied by the user).
Sigh. "diff", not "patch". Sorry, that's my first one. Fixed.
