    make(1): do not create empty shell files in jobs mode

    In a chain of dependencies such as "all: build; build: do-build", the
    intermediate targets do not have any commands.  In jobs mode,
    nevertheless, an empty file was created and fed to the shell.  This was
    unnecessary.  See jobs-empty-commands.mk.

    The case of the special command line "...", which was suggested on
    current-users, is not optimized since it doesn't occur in practice.

    Suggested by Mateusz Guzik on current-users:
