Details:

Example code:


function code_folding_demo

for x = 1:5   % Code folding is working, but not indicated

  % ^^^ please remove empty line above *or* enter some white space ^^^

  a = b + c;
end

for x = 1:5   % OK
  a = b + c;
end


In line 3, there is no [-] code folding indicator visible in the folding
ruler. Nevertheless, it is possible to click on the invisible indicator to
open and close folding. It will work as expected.

Removing line 4 *or* entering some white space in line 4 will work around this
glitch. Notepad++ is showing exactly the same behaviour, maybe it is inherited
from Scintilla.

Example code and screenshot attached.
