There is a problem, I think it was introduced in 2012-02-14 but I'm not
absolutely certain.
bin> ./ksh --version
version sh (AT&T Research) 93u+ 2012-05-31
bin> echo foo\\\\bar | read baz
bin> echo $baz
foo
Adding a
was_escape = 1
to the skip: block in read.c fixes this, but this may cause problems for
S_QUOTE which jumps into that block for some reason. My suggested fix is the
below, which seems to work, but I haven't tested all possibilities
Thanks,
Anders
