The problem isn't Python's string translation, it is gnuplot's.  The
situation is that there is a valid python string containing a filename,
and that filename has to be passed to gnuplot quoted in such a way that
gnuplot interprets it as the original string.

For all characters except "'" (single-quote), simply single-quoting the
string to gnuplot works.  But there doesn't seem to be any way to pass a
single quote to gnuplot within a single-quoted string (e.g., '\''
results in a two-character string containing "\" and "'").

So if we need to support filenames with single-quotes, we have to use
gnuplot's double-quoted format.

I think double-quoted strings should work OK, but we have to quote both
'"' (double-quote) and "\" (backslash).  It might not be necessary to
handle double-quote for windows filenames, but we should handle it
anyway for generality.  Then, I believe, we could use the same quoting
code for all operating systems.
