It seems that I was mistaken in my assumption that '\' is mapped to a
multibyte character in Shift_JIS. According to John Cowan, "the
character at #\x5C is *functionally* a backslash that is *displayed* as
a yen sign".
It seems that this is not actually a bug in 'scm_i_mirror_backslashes',
so I'm closing this bug.
