tty_getlin cleanup (trunk only)

The presence of conditional code for both UNICODE_WIDEWINPORT and
NEWAUTOCOMP in hooked_tty_getlin() was making it be pretty hard to read.
This simplifies the UNICODE_WIDEWINPORT parts similar to what was done in
topl.c a year or two back.  The NEWAUTOCOMP parts are still cluttered.

     This compiles successfully with UNICODE_WIDEWINPORT enabled but that
configuration is otherwise untested.
