Highlighter::highlight_candidate() candidate argument should be Completer::Candidate

[tobiasvl]

See FIXME comment here:

rustyline/src/highlight.rs

Line 45 in 4d48e58

candidate: &'c str, // FIXME should be Completer::Candidate

What's the reason this isn't fixed? Can it be fixed?

I had to work around this and highlight the candidates in Completer::complete() instead.

I guess it can be fixed but not easily.
See #427, #207.
