Minor expansion problem

Minor expansion problem

[Peter Stephenson]

Can anyone would explain why I get

% echo foo and, just to be different, bar >foo
% echo `cat foo`<TAB>
     ->foo\ and,\ just\ to\ be\ different,\ bar.

with the _expand completer (and complete-word bound to TAB), but what I
expect, i.e. no backslashes, with the _expand_word widget?  I've stared at
my styles but can't see what might be causing it.

It's in part because you used backticks.  Expanding $(...) doesn't put
in backslashes, but expanding `...` does.  This appears to be happening
because the ${(e)exp} at _expand line 83 returns one word for `...` but
an array for $(...).

} but what I expect, i.e. no backslashes, with the _expand_word widget?

Hrm, I get backslashes in both cases.  Are you sure you're using the
_expand_word widget (^Xe) and not the builtin expand-word (^X*) ?

} I've stared at my styles but can't see what might be causing it.

The only style that I can see getting involved here is the "glob"
style, in contexts :completion:expand:* and :completion:expand-word:*.
See _expand line 98.
