Subject: Fix _command_list() function for empty command sets
X-Git-Url: https://git.distorted.org.uk/~mdw/stgit/commitdiff_plain/c391c4c17fb67567bad4a28f0010e59378426956

Fix _command_list() function for empty command sets

The alias commands are not real StGit commands and the corresponding set
(kind) defined in stgit/commands/__init__.py is empty. This leads to a
KeyError in the _command_list() function. The patch ignores empty sets.
