Well, if those copies done on  each editing operation this will mean 
you have max 50 editing steps back.
But I agree limiting it to some saner number will be improvement.

I think I already saw some mtime (modification time?) reading in mwindow.C 

int MWindow::load_plugin_index() here .....

Note, I already added warning to this operation and option to hide it in
runtime altogether ... 

Patches usually applied with 'patch'

in cin source folder

git apply -v /path/to/patchfile.diff

or

cat /path/to/patchfile.diff | patch -v -p1 (or p0)

it should report failures or success on patching.
