#304 Wrap on spaces only if possible

[Mercury]

TXC VERSION: 2.0 alpha 3 build 1118
OS VERSION: Windows XP SP3

STEPS TO REPRODUCE:
1. Turn "Word wrap" on
2. Write an equation w/o spaces such as $x$
3. Start to add characters before the equation until TxC wraps

EXPECTED BEHAVIOR: the entire equation should remain on the same line

ACTUAL BEHAVIOR: wraps like
(some text here) $
x$

You are right. I noticed this, too. And it is annoying.

However, we have to rewrite larger parts of the syntax highlighting to do this properly. It is part of the Scintilla LaTeX parser.
