Patch for off-by-one error in scan-skel.l |

I guess that bison.simple, etc. are so firm that you guys never
noticed this one; I, on the other hand, am developing a new, bug-prone,
experimental skeleton, so I did :-).
A #line directive, such as
#line 15 "somefile.c"
means that the NEXT line of the file containing it corresponds to line
15 of somefile.c. The current scan-skel.l code, however, puts the
line number *of the #line directive itself* in place of __oline__,
causing mildly annoying behavior when debugging.
OK to commit?

[P.S. Akim: Perhaps I did not understand your last message
re: Patch b4_uint_type and b4_sint_type range problem. Were you
asking me to commit that patch?]
