[bitbake-devel] [PATCH 1/1] bitbake-diffsigs: fix traceback with no arguments

[Paul Eggleton]

In the move over to argparse we've made the two signature file arguments
optional and thus if -t is not in use we need to explicitly check if at
least one signature file has been specified - and if not, show an error
and the command-line help.
