The use of WRDE_NOCMD prevents command substitution. If the flag
WRDE_NOCMD is set then no command substitution shall occur and
the error WRDE_CMDSUB will be returned if such substitution is
requested when processing the words.
The manual page as-is makes it seem like the command substitution
occurs, and an error is returned *after* the substitution.
This patch clarifies that.
Patch against trunk.
