        src/bin/sh: miscbltin.c sh.1

Log Message:
It appears that POSIX intends to add a -d X option to the read command
in its next version, so it can be used as -d '' (to specify a \0 end
character for the record read, rather than the default \n) to accompany
find -print0 and xargs -0 options (also likely to be added).

Add support for -d now.   While here fix a bug where escaped nul
chars (\ \0) in non-raw mode were not being dropped, as they are
when not escaped (if not dropped, they're still not used in any
useful way, they just ended the value at that point).
