Everybody must be on spring break.

} I don't know exactly why this was broken, but my patch in 13992 fixes it.
} So maybe I should commit that patch after all.
I've now got one additional thing fixed. In any version of zsh up to
4.0.1-pre-3, try this:
% foo='any random string'
% echo $foo[(i)ran
0(i)ran
The correct output would be one of these:
zsh: invalid subscript
zsh: bad pattern: any random string[(i)ran
zsh: bad pattern: string[(i)ran (shwordsplit)
any random string[(i)ran (nobadpattern)
It's fairly difficult to get zsh to treat that open-bracket as anything
other than the start of a subscript, so the first of those is easiest,
and is what I've done. However, that also means that:
% echo $foo[ran
zsh: invalid subscript
In 4.0.1-pre-2 that gives `any random string[ran' (regardless of the
setting of badpattern, which is arguably also wrong).
One additional question: I think it'd be straightforward to make this
be parsed as all one word:
% echo $foo[(i)dom str]
I.e. the space inside the [ ] could implicitly be quoted. Currently
it's necessary to use "$foo[(i)dom str]" to get an embedded space in a
subscript. I can't think of any way in which such a change would break
a currently-working script. Is it worth trying?
