PATCH: _look

[Tanaka Akira <akr@m17n.org>]

This is a completion function for `look'.  It calls `look' itself to
find completions.

Apart from that, I found that some functions using a state of
_arguments such as _gzip declare `curcontext' instead of `context'
which is specified by zshcompsys(1).  Is `curcontext' obsolete?
