Subject: [PATCH] wordexp.3: Make it clear that WRDE_NOCMD prevents command substitution.
Date: Wed, 19 Nov 2014 14:45:12 -0500	[thread overview]
Message-ID: <546CF348.5080400@redhat.com> (raw)

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.
