KiCad used to ask user if he wants to recover files from autosave file but currently it doesn't work this way. Instead the autosave is silently removed. I think that the function which did that is the "CheckForAutoSaveFile" (it contains the question "Well this is potentially embarrassing [...]". Is it supposed to work? It doesn't work for me neither on windows nor linux.
Also it seems to me that default autosave intervals are random. I installed new stable KiCad on two computers with windows and the values were -27 minutes on one and some thousands of minutes the second one.

Well, this is embarrassing. It appears that this function is not working correctly. It is _only_ called when loading pcbnew files (should also be called for eeschema) AND it uses the eeschema autosave prefix instead of the pcbnew prefix.
So I'll propose two actions here:
1) Unify the autosave prefix strings as there doesn't appear to be a reason for them to be different
2) Add this function to eeschema.
Objections?
