log: diagnose -L used with pathspec as an error
The -L option is documented to accept no pathspec, but the
command line option parser has allowed the combination without
checking so far. Ensure that there is no pathspec when the -L
option is in effect to fix this.
Incidentally, this change fixes another bug in the command line
option parser, which has allowed the -L option used together
with the --follow option. Because the latter requires exactly
one path given, but the former takes no pathspec, they become
mutually incompatible automatically. Because the -L option
follows renames on its own, there is no reason to give --follow
at the same time.
The new tests say they may fail with "-L and --follow being
incompatible" instead of "-L and pathspec being incompatible".
Currently the expected failure can come only from the latter, but
this is to futureproof them, in case we decide to add code to
explicititly die on -L and --follow used together.
