mcedit annoying syntax highlight changes

[Jan Engelhardt]

Hi,


starting with mc 4.6.2, there have been changes to the syntax 
highlighting, specifically displaying whitespace.

int main(void)
{
<------>if (this) {
<------><------>that;
<------>}
}

While I welcome this, I sometimes prefer to have it turned off[1]. 
Looking at the source code, I see no tunable to control displaying 
whitespace, nor a color setting to make it at least the same as the
background color.

int visible_tabs = 1, visible_tws = 1;
all other uses of these variables are read-only.
