PARSE from SwiftX/Src/Interp.f

The target PARSE eats leading delimiters. PARSE is not supposed to do
that, at least from how I read the standard. It is not mentioned in the
comments for the target PARSE that it is non standard.

WORD is supposed to that, but not PARSE. The PARSE on HOST works correctly.

Given the 2 following example strings:
a,,,,,,,,,,DDD,,,,,,,,,,,333,
a,d,d,e,e,f,g,h,h,j,DDD,a,s,d,d,d,e,e,e,e,e,333,

"['] , PARSE" works correctly on HOST for both (same number of fields
are parsed for each string). Zero length strings are returned for the
empty fields, as I would expect.

The target PARSE provided it is different, only 'a', 'DDD', and '333'
are returned.

I'm not using the target resident interpreter, I just need to use PARSE.
