[M3devel] Text processing

[Jay]

Are the nulls included in the length?
 
If so, that'd be a likely bug. If not, it'd be a /possible/ feature. Seriously.
I deal with "lengthed" strings a lot, but my "duplicate" and "concat" functions add them, and don't put them in the length, for interop with all the other code out there..
But it is a little sleazy my pattern and we do have explicit functions for C interop.
