PATCH: metaflac completion

[Jesse W <jessw@xxxxxxxxxxx>]

I've written a first version of a z shell completion function for the 
FLAC metadata editing program, metaflac; right now it doesn't complete 
any of the option arguments that arn't files, but it handles the 
various options, and handles looking only for FLAC files (with the -g 
option of _files).  This will be more or less my first zsh completion 
function, so any suggestions would be greatly appreciated.

I plan to implement completion for the tag options, so that, i.e. 
`metaflac foo.flac --show-tag=` would automatically get a list of the 
tags in the file in the background and complete their names at that 
point; also, I'd hope the --set-tag= option would have a preset range 
of tags to set.

My eventual goal is to make metaflac (with zsh completion) into a 
more-or-less comfortable FLAC metadata editor.

The file is attached.  If the mailing system mucks it up, it's also 
available at
