Then perhaps git-reset should do "co HEAD path" too if --index is not specified?
To sum up:
 - git reset HEAD path -> git checkout HEAD path
 - git reset --index HEAD path -> git-ls-files HEAD path|git
update-index --index-info
 - git reset HEAD (without path) -> the current behaviour

Because  <commit-ish>  may be missing, there is some ambiguation here.
