#1692 Code folding issue in matlab files

[Torsten]

In matlab files, the "-" marker for code folding is not shown when an empty line follows the line that is opening the block as can be seen in the attached screenshot. SciTe version 3.5.3 compiled for GTK+ 2.24.23

[Neil Hodgson]

The Matlab folder is very simple and uses indentation to determine fold levels. This was copied from the Python folder but is not really suitable as Matlab uses keywords for block structure, not indentation.

Fixing this properly requires someone interested in Matlab to rewrite the folder.
