Subject: [PATCH] _describe and literal \n
Message-ID: <20160723180430.GA22451@tarsus.local2>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Disposition: inline
User-Agent: Mutt/1.5.23 (2014-03-12)

Current behaviour:
[[[
$ zsh -f
% autoload compinit
% compinit
% _f() { a=( $'foo:hello\nworld' $'bar:lorem\nipsum' ); _describe descr a }
% compdef _f f
% f <TAB>
bar  -- lorem
ipsum
foo  -- hello
world
]]]

Proposed patch:
[[[
diff --git a/Src/Zle/computil.c b/Src/Zle/computil.c
index e8f0a6f..9e3ea3c 100644
--- a/Src/Zle/computil.c
+++ b/Src/Zle/computil.c

             else
                 str->desc = NULL;
             *tmp = '\0';
]]]

Gives:
[[[
% f <TAB>
bar  -- lorem\nipsum
foo  -- hello\nworld
]]]

Is this fix correct?
