And this will all unfortunately change with 2.9.x and later versions,
which do nothing special for backslash in single-quoted strings (for
compatibility) but do expand backslash escapes in the usual way when
they appear in double-quoted strings.

But, you still have the problem that external programs may interpret
the backslashes, so even if Octave passes them along unmolested to
some output file, a program like fig2ps may need to have them doubled
up.
