Remove unreachable argument presence check (handled by `getopt`)
Merge allocation paths into a single `realloc` call
Avoid searching for string lengths multiple times
Tiny (compatible) change: no space between last dependent and colon if
`-MT` or `-MQ` is specified
* Implement -Wtruncation=level
-Wtruncation=0 is the same as the current -Wno-truncation.
-Wtruncation=2 is the same as the current -Wtruncation.
-Wtruncation=1 is the new default; it's less strict, allowing
N-bit values to be between -2**N and 2**N (exclusive).
* Implement generic "parametrized warning" system
* Test more `Wtruncation` variants

* Reword label definition docs
A bunch of short sentences isn't very readable, this should be better
* Use correct wording for "computing difference"

* Explain how to define a label before mentioning local ones
* Move double-colon paragraph to make the explanation flow better
* Clarify what a label's value is

`startCapture` did not initialize `lexerState->atLineStart`;
its final value is a consequence of the separate but similar
behaviors within `lexer_CaptureRept` and `lexer_CaptureMacroBody`.
`DEF`, `REDEF`, etc disable EQUS expansion, and reading
macro or OPT arguments sets the lexer to raw mode.
Syntax errors resume normal parsing at the line's end,
but should resume normal tokenization even before that.
This message is only printed for identifiers parsed as
`T_LABEL` (since they're at the start of a line) but
already defined as macros. Otherwise it may not be
relevant, e.g. for `MyLabel;:` or `My Label::`.
Fixes#881 by moving the task from the lexer to the parser.
This both alleviates the need for backtracking in the lexer,
removing what is (was) arguably a hack, and causes tokenization
boundaries to be properly respected, fixing the issue mentioned above.

* Reinstate PUSHS clearing the SECTION scope
Otherwise you can use `PUSHS` to simulate the old `ds -21`, and possibly cause bugs
* Have PUSHS push LOAD block state as well
It does not make sense not to, and coud cause bugs.
Redefining an EQUS constant will now update its filename,
like redefining a SET/= constant.
Attempting to redefine as EQUS a non-EQUS constant will
print an appropriate error message.
This also standardizes on `sym` versus `symbol` as a
variable name (which pairs with `symName`).
