Likely users don't care too much about the name of the saved file,
so they likely use the default ones. If they mess up, they also
likely want to return to the original, but, d'oh, it's overwritten.
Don't let this happen, enforce a non-original file name for user
saves.
In other words: don't let users shoot themselfs into their foot.
It was certainly a good idea, but also always a suspect of
malfunctions and as such, almost never used. Newer code
organisation moves most of the code behind it to dda_clock()
anyways, so it also became mostly obsolete.
Rest In Peace, STEP_INTERRUPT_INTERRUPTIBLE, you were matter
of quite a number of interesting discussions and investigations.
