cmake --help case sensitivity

[David Faure]

$ cmake --help exec_program
Help argument "exec_program" is not a CMake command.  Use --help-command-list to see all commands.
$ cmake --help EXEC_PROGRAM
[works]

Since commands are case insensitive, can --help be fixed to be case insensitive as well?
Thanks.
