for i in $*

    case "$i" in
    -h|--h|--he|--hel|--help)

gitk "$@"
exit $?

I'm not sure if this would be a worthwhile addition. Right now, you cannot type gitk --help at the command line to get usage instructions. This is due to the fact that wish does not allow printing to STDOUT.

It is possible to use man gitk or git help gitk, but the lack of gitk --help can be confusing.

To work around this, a launcher script can be used to look for --help on the command line. If it is present, then print usage instructions and exit. If it is not, then call gitk.
