Careful examination reveals that we do actually treat it as a whitespace
character. Except when looking for blank lines in literate scripts!
The following patch fixes that:
diff -c -r1.28 input.c
*** input.c 1998/01/29 18:52:20 1.28
--- input.c 1998/02/19 19:00:30
***************
*** 562,568 ****
litLines++;
return;
}
! while (c0==' ' || c0=='\t')/* maybe line is blank? */
skip();
if (c0=='\n' || c0==EOF)
thisLineIs(BLANKLINE);
--- 562,568 ----
litLines++;
return;
}
! while (c0 != '\n' && isIn(c0,SPACE)) /* maybe line is blank? */
skip();
if (c0=='\n' || c0==EOF)
thisLineIs(BLANKLINE);
This will be in the next release but it should be easy enough to apply
it yourself on Unix.

Actually, the standard C library functions delete ^M for us so we
never had to explicitly worry about this before.
