This has always been broken. The '((' parse doesn't have a tokstr
value (cf. comments about parsing "for (( ... ))" in bufferwords()
[hist.c]). Prior to recent fixes to backtrack this properly, the
error was even worse:
torch% print $ZSH_VERSION
4.2.0
torch% print -rl - ${(z):-'(( e x y'}
e x y
(
e
x
y
torch%
There's also an issue of how to treat "e" in this example. If the
double parens are taken as math context, then "e" is a single double-
quoted token, otherwise it has to be decomposed into shell words. As
you can see, 4.2.0 parses it BOTH ways (eek).
I don't have an answer for where the right place to "output" the parens
would be; the backtracking makes this ugly.
