  It can be really tricky debugging a complex makefile that's full of function
calls and evals, so here's a patch that adds lots of debugging output from the
parser.  You get to see exactly what the parser's seeing and what it thinks
it's doing about it.

        * doc/make.texi:  Documented new 'p' option letter to '--debug='.
        * debug.h (DB_PARSER):  New debug flag bit.
        * main.c (decode_debug_flags):  Let 'p' set DB_PARSER in db_level.
        * read.c (eval):  Added a whole lot of debug under DB_PARSER.

Can't think of a witty .sigline today....
