Subject: buggy CSH_NULL_GLOB when a pattern is at the command position
Date: Fri, 1 Jan 2016 05:00:52 +0100	[thread overview]
Message-ID: <20160101040052.GA1808@zira.vinc17.org> (raw)

When CSH_NULL_GLOB is set and the command line contains only patterns,
a "no match" error is not reported.

Without CSH_NULL_GLOB:

zira% []
zsh: no matches found: []

With CSH_NULL_GLOB:

zira% setopt CSH_NULL_GLOB
zira% []
zira% [] []
zira% [] echo foo
foo

but

zira% echo []
zsh: no match

is OK.

Moreover, I wonder whether when a no-match pattern is at the
command position, one should always get an error (if possible).

BTW, with older zsh versions, such as 5.0.7, [] was regarded
as a bad pattern (instead of a pattern that doesn't match).
Has this changed on purpose?
