getc() != EOF

[Brandon Allbery]

	The local "lint" tells me that ((ch = getc ()) != EOF) is illegal on
IBM-based Cs.  This fits in with the (assumption) that an IBM/370 C would use
EBCDIC, NOT ASCII, and all 8 bits of the character data are significant, so
the ONLY way to trap an EOF would be the feof () function.  (OK, for normal
text files, 0xff is not normally used, but they may have thought they were
stretching it.  They don't use 0x0a either, usually, although I've never run
Unix on an IBM.)
