Not too fond of having to modify `mandoc.css`, but I did my best to
modify as little as possible
rgbasm tries to optimize any loads from/to $FF00-$FFFF and generate
LDH 2-byte opcodes instead of regular LD 3-byte opcodes. This is a bit
inconsistent as it only works for constant values. If a load is trying
to access a label in a HRAM floating section, or a section found in a
different object file, this optimization doesn't work.
This means that a simple refactor or code could allow rgbasm to perform
the optimzation or prevent it from doing so. For certain projects, like
disassemblies, this is a problem.
This patch adds flag -L to rgbasm to disable the optimization, and
doesn't change the behaviour of any other existing code.

Newlines have to be handled before comments or comments won't be able to
handle line endings that don't include at least one LF character.
Also, document an obscure comment syntax: Anything that follows a '*'
placed at the start of a line is also a comment until the end of the
line.

Previously, JR was only allowed if the destination label was in the same
section as the JR. This patch removes this restriction. The check to see
if the relative value overflows is now done when linking the ROM.

PRINTV prints integers in hexadecimal, PRINTI prints them in signed
decimal. For example:
PRINTT "Error at line "
PRINTI __LINE__
PRINTT "\n"
