mcedit default indentation settings cause mixture of tabs and spaces

By default, mcedit’s indentation settings are: 8 units per tab, use tabs, and use fake half tabs.

This causes problems because fake half tabs are in fact tabsize/2 space characters, and as anyone who has ever indented source code knows: either use tabs, or spaces, but make up your mind, else havoc is guaranteed.

I find it especially unwise to propagate such a counterproductive setting as default. I think Fake Half Tabs would be much better turned off -- whether people use tabs or spaces, and how many of them is a wholly different issue altogether.
