#49 backslash in text treated as escapes

[Jan Lindblom]

When saving content with backslashes in it, some LaTeX
code for example, the backslashes are treated as
escapes. That is, if i save "\sqrt{x}" it comes out as
"sqrt{x}" while "\\sqrt{x}" comes out as "\sqrt{x}".
Until I edit the page again that is, then the
backslashes will need updating again to "\\" so that
they won't disappear when I save again.

This might be platform dependent but I doubt it, I
haven't got a windows server to verify on though.
