06b57aa1ce Avoid unnecessary "overwriting a non-zero byte" warnings 
- Don't warn if the non-zero byte being written is the same as the original byte
- Add a `-O` / `--overwrite` flag to silence all such warnings

Fixes #897

80a376f045 Syntax errors resets the lexer right away 
`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.

0068c1375c Syntax error message hints to indent macro invocations 
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::`.

c06985a7ad Fix incorrect lexing of "$ff00+c" (#882) 
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.

21b59c4651 Reinstate PUSHS clearing the SECTION scope (#870) 
* 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.

27f38770d4 Parentheses in macro args prevent commas from starting new arguments

e596dbfc80 Make failed macro arg expansions non-fatal 
Expanding empty strings is valid but pointless;
macro args already skipped doing so, now other
`beginExpansion` calls do too.

This also fixes failed interpolations (which were
already non-fatal) to continue reading characters,
not evaluate to their initial '{' character.
