Prompt percent completion for truncations

Prompt percent completion for truncations

[Bart Schaefer]

This is cute but unhelpful:

[         -- truncation from who knows where

Furthermore, completion after that doesn't work right:

% PS2=%[
parameter
(list of parameter names elided)
% PS2=%\[
(literally nothing: no suggestions, no beep)

If we're going to include %[ in the completions, it should continue
with %[< or %[> ... but my vote would be to just remove that because
it's a deprecated form of %< and %> respectively.  There is also this:

% PS2=%\<
replacement string
% PS2=%\[\<
number

The latter is wrong, of course; both of these should behave the same.

I have a feeling this is my fault, but I think the statute of
limitations has expired for this particular crime. (zw/30466)

I'm pretty sure I was unaware of the intricacies of $comp_state[quote]
back then, and did most of my testing inside single quotes.

Hah!  Yes.

The quoting actually doesn't matter, same thing happens with
backslash, single, or double quotes.

That seems to be coming from
  _message -e ternary-prompt-expression number
which I think arises from treating as a ternary anything that doesn't
match the preceding list of specs, but I'm not certain.
