Yeah, I'd noticed that one too :-(. I think the whole jsonpath patch
needs a sweep to bring its error messages into line with our style
guidelines, but no harm in starting with the obvious bugs.

Right. I'm not really sure why we're bothering with anti-backtracking
here, or with using speed-rather-than-code-space lexer optimization
options. It's hard for me to credit that any practically-useful jsonpath
pattern would be long enough for lexer speed to matter, and even harder to
credit that the speed of the flex code itself would be an important factor
in the overall processing cost of a long jsonpath. Still, as long as we
have the code it needs to be right.

I doubt it's worth the trouble, per above.
Patch LGTM, pushed.
