Hello!

sparse doesn't handle multiple -include directives.  Variables "include"
and "include_fd" have file scope in lib.c.  The file for inclusion is
processed only once in sparse_initial() after the command line has been
processed.

It seems to me that the existing add_pre_buffer() mechanism can be used
instead.  I'm just a bit worried why it wasn't done like this in the
first place.
