bug#20127: bug in stty

[Morris Keesan]

stty --version:
stty (GNU coreutils) 8.13

uname -a:

==================================================================
bug:
      stty erase ''
sets erase to <undef>.  This may be intentional, but seems like a bug, since
this behavior is undocumented, and the stty man page says,
"special values ^- or undef used to disable special characters."

I haven't bothered testing, but I assume that an empty argument gets treated
as undef for all special characters.
