Short description in man pages: * Use imperative form Command help (cobra.Command.Short): * Capitalize first letter * Use imperative form * Remove ending full stop when the short description only contains one sentence without any commas Command help (cobra.Command.Long): * Capitalize first letter unless the sentence starts with a command "podman command ..." * Use imperative form when the long description is identical or almost identical to the short description. This modification was only done in a few places. Command tables: * Use imperative form in the "Description" column [NO NEW TESTS NEEDED] Signed-off-by: Erik Sjölund <erik.sjolund@gmail.com>
