sym_SetMacroArgID used a `sprintf` that could write no \0.
In practice this was benign because %u cannot print 256 chars,
but better future-proof this.
While working on #392, I noticed that the macro-@ test (as well
as the line-continuation test, but for that one see #393)
printed an additional '@(-1)' entry which doesn't make sense.
c75a953 broke my (previously-working) project that defined, via
macros, 'sizeof_.player'.
A test was added to confirm that those are indeed accepted
outside of macros.
Should partially cover #178 and close#270.
This allows printing numbers in different bases and without the dollar prefix
This is especially useful in macros because the dollar isnt a valid character
for symbol names, requiring heavy `STRSUB` usage.
When trying to fix a section becoming too large, the size it reached is necessary to know whether to optimize away a few bytes or split it entirely.
This error is also commonly encountered when INCBINing too large a slice of a file, in which case the amount of bytes by which the section is too large is again an useful information
