The logic to insert an implicit command has always been a bit broken but it was masked by another bug fixed in the patch ("patman: Don't look at sys.argv when parsing settings"). Specifically, imagine that you're just calling patman like this:
patman -c1
After the parse_known_args() command then the "-c1" will have been parsed and we'll have no command. The "rest" variable will be an empty list. Going into the logic you can see that nargs = 0. The implicit insertion of send ideally would create an argument list of: ['-c1', 'send'] ...but it doesn't because argv[:-0] is the same as argv[:0] and that's an empty list.
Let's fix this little glitch.
