 question marks
Date: Fri, 27 May 2016 17:22:53 -0400

[Message part 1 (text/plain, inline)]

In emacs -Q, placing the point as indicated below causes eldoc to display “a: (X\=\?)” instead of “a: (X?)”.

    (defun a (x?)) ;; Eval this
    (a) ;; <-- place point before parens

This “\=” looks like the escape sequence that we use in docstrings; maybe that's a sign of something?

Clément.

Thanks for the report. This is a regression against 24.5.

Eli, do we make it a blocker?

Indeed, it is.

> Eli, do we make it a blocker?

I don't think so.  It sounds like a marginal use case that's easy to
avoid (this isn't Scheme, so predicates should be named SOMETHING-p,
not SOMETHING?).  But if someone wants to make a case why it should be
blocking, I'm all ears.

I also think that if a simple solution exists, we should fix this on
the release branch.

Thanks.

It was trivial to fix, so I just did.
