[PATCH][TRIVIAL] triple question marks in ppa.c

[Rik van Riel]

Don't ask me why???  Triple question marks are a C trigraph in ansi C.

                       ^^^^^^^^^^^^^^^^^^^^^

[1]'ISO/IEC 9899:1999  Programming languages  --  C' says in §5.2.1.1 that
C trigraph sequences are:

??=     #         ??)     ]         ??!     |
??(     [         ??'     ^         ??>     }
??/     \         ??<     {         ??-     ~

"No  other  trigraph  sequences exist", I didn't look [2] 'Corrigendum 1,
ISO/IEC 9899:1999/Cor 1:2001', but I think that they were not modified.

And inside of comments there are not trigraph substitutions, at least
in theory §6.4.9.

I only found a few in 2.4.22-bk30, aka 2.4.23-pre7:

thanks to fix them ;-)
