ncurses-5.9-20110716.patch changes linux term to use SI/SO (use G1 charset)
for selecting alternate character set; however, it kept acsc to use CP437
codes - it had a chance to work on non-unicode terminal only if G1 was mapped
to CP437 map, which is not the default; the default for G1 is VT100 map, which
works with VT100-specific acsc string - and that's what this patch changes.

 # Using SI/SO has the drawback that it confuses screen.  SCS would work.
 # However, SCS is buggy (see comment in Debian #515609) -TD
