I looked at the script and these texts are hard coded in there. I don't use zsh myself and won't be doing this, but this information should be now available from git binary so you can lower maintenance cost for the zsh completion script. > > 1114$ git commit -<tab> > Completing option > --all -a -- stage all modified and deleted paths > --allow-empty -- allow recording an empty commit > --allow-empty-message -- allow recording a commit with an empty > message > --amend -- amend the tip of the current branch > --author -- override the author name used in the > commit Hm.. no idea where this is from. Maybe zsh can extract "git <command> -h"? Anyway it does not matter. -- Duy
