Make argument parsing a bit more robust
Currently, when running mfh with a flag like --help the user gets
a confusing error message from expr(1) like the following:
> expr: illegal option -- -
> expr: usage: expr [-e] expression
>
> revision "--help" should be a number
This is not helpful. Instead, make sure that any arguments specified by the
user are handled properly by expr(1). This results in a much cleaner error
message:
> revision "--help" should be a number
