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.

7a587eb7d6 Use midrule action values for captures' terminated status 
Bison 3.1 introduces "typed midrule values", which would write
`<captureTerminated>{ ... }` and `$$` instead of `{ ... }` and
`$<captureTerminated>[1-9]`, but rgbds supports 3.0 or even lower.
