alias: add support for aliases of an alias
Aliases can only contain non-alias git commands and their arguments, not other user-defined aliases. Resolving further (nested) aliases is prevented by breaking the loop after the first alias was processed. Git then fails with a command-not-found error. Allow resolving nested aliases by not breaking the loop in run_argv() after the first alias was processed. Instead, continue the loop until `handle_alias()` fails, which means that there are no further aliases that can be processed. Prevent looping aliases by storing substituted commands in `cmd_list` and checking if a command has been substituted previously. While we're at it, fix a styling issue just below the added code.
