[issue2457] add --help and -h options to pdb

[Benjamin Peterson]

New submission from Benjamin Peterson <musiccomposition at gmail.com>:

If --help or -h are used as options for pdb, pdb unhelpfully exits with
"file -h cannot be found." This makes it more user friendly and prints
the usage if those options are passed.
