Now, diagnostic messages are prepended with the source path.
But if the problem comes from a file included directly from
the command line like:
sparse -include some-buggy-file.c
the prepended message will be:
(null): note: in included file ...
because there isn't a source path yet.
So, initialize the source path to "command-line".
