Of course: each mode sets up its own `syntax-table' where the meaning of
each char is described.  So if in Rexx a \ should not escape the next char,
the syntax-table should be changed.
Currently rexx-mode.el does:

  (modify-syntax-entry ?\\ "\\" rexx-mode-syntax-table)

which as that \ should be treated as an escape char.  So either this line is
in error, or the \ should sometimes be treated as an escape char and
sometimes not.  I don't know anything about the syntax of Rexx, so I have no
idea when \ escapes and when it doesn't.  E.g. how do you escape a " inside
a string in Rexx?
