[PATCH] zed: fix argument parsing

[Eric Cook <llua@xxxxxxx>]

Also reported in IRC:

% fned +vi-git-applied-string
zed:4: bad option: -v
zed:4: bad option: -i
zed:4: bad option: --
zed:4: bad option: -g
...

This could optionally be fixed by changing getopts "fbx:" to
getopts ":fbx:" so the `unknown options' are silently ignored.
