magic-space and pipe symbols in parentheses

[Frank Terbeck <ft@bewatermyfriend.org>]

Hey list,

Simon Désaulniers found this (the ^ in the line below indicates the
cursor position at a zsh prompt):

zsh% $(foo) bar
          ^

Now insert "| " with space being bound to magic-space:

  bindkey ' ' magic-space

...to get this (the " bar" is gone):

zsh% $(foo| )
            ^

This works from "zsh -f" with the additional bindkey I mentioned.

I've bisected this down to:

commit 4073a6655cafc78728cb126cfe44e89cc7ba720a

    39815: Read input to end on parse error in $(...) inside a string.

    This allows ${(z)} to output the whole string, although we can't do
    word splitting from the error onwards.


Not sure how this is related to magic-space, but this is what I get.


Regards, Frank
