:/ that patch allows `zed -foo' to edit the function `-foo'.
It should error due to unknown options in my opinion.


I think editing files/functions that start with `+' or `-' should require -- to be used.

This patch silents the bad options errors, shown in my first example and zed will show the help message.
To edit the function `+vi-git-applied-string', `--' is needed.
