9081feab51 Reinstate macro arg scan distance 
Used to be broken, so it was removed, but doing so prevents escaping them.
So it was instead put back in, but with corrected behavior

81a77a9b88 Re-implement block copy to avoid expanding macro args 
They were expanded during the capture, and there was no easy way to
avoid expanding them (believe me, after three hours and somehow an OOM, I
gave up trying).

38bda7e1bb Fix string expansion reporting

149db9a022 Fix incorrect freeing of expansions 
Freeing an expansion should free its children, not its siblings...
Fixes a use-after-free reported by scan-build. Nice catch!

fed252bc49 Fix nested expansions being incorrectly handled 
The biggest problem was simply that the length of children expansions was
not accounted for when skipping over the parent... this took a lot of
arduous debugging, but it finally works!

61b2fd9816 Add string expansion reporting 
And fix line counting with expansion-made newlines.
This has the same bug as the old lexer (equs-newline's output does not
print the second warning as being part of the expansion).
Additionally, we regress equs-recursion, as we are no longer able to
catch this specific EQUS recursion. Simply enough, the new expansion
begins **after** the old one ends! I have found no way to handle that.

4c9a929a14 Implement almost all functionality 
Add keywords and identifiers
Add comments
Add number literals
Add strings
Add a lot of new tokens
Add (and clean up) IF etc.
Improve reporting of unexpected chars / garbage bytes
Fix bug with and improved error messages when failing to open file
Add verbose-level messages about how files are opened
Enforce that files finish with a newline
Fix chars returned not being cast to unsigned char (may conflict w/ EOF)
Return null path when no file is open, rather than crash
Unify and improve error printing slightly

Known to be missing: macro expansion, REPT blocks, EQUS expansions

6dc4ce6599 Implement infrastructure around new lexer 
The lexer itself is very much incomplete, but this is intended to be a
safe point to revert to should further implementation go south.
