[QScintilla] Matlab Lexer

[Mikhail Murzin]

John,
You can use a Matlab lexer from JuffEd project:
http://juffed.svn.sourceforge.net/viewvc/juffed/0.9/src/app/qsci/lexers/my/

<http://juffed.svn.sourceforge.net/viewvc/juffed/0.9/src/app/qsci/lexers/my/>
Phil,
Feel free to include it in QScintilla.

Best regards,
Mikhail.
