Tim Schumacher c6d75bc17a 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.
