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.
