The changes for that are minimal. With them, Stephane's math-garbles
handle the ellipsis more cleanly:
% printf '%d\n' '1+|ÃÃÃÃÃÃ'
zsh: bad math expression: operand expected at `|\M-C\M-c\...'
0
% ((1+|ÃÃÃÃÃÃ))
zsh: bad math expression: operand expected at `|Ã?Ã?Ã?...'
And the ${..?..} error messages come out as expected:
% err=$'one\ntwo'
% print ${a?$err}
zsh: a: one
two
I'm not sure what if anything to change about yyerror() in parse.c,
it's already untokenize()ing what it passes and maybe that shouldn't
be "nice" anyway?
No patch until I have more feedback, this time.
