Maybe we can find a better name than "perform_autostash"? It is not
clear whether this is the "saving" or "applying" part of the autostash,
I think.
Maybe `save_autostash()`? And maybe instead of `path`, the parameter
could be `save_hash_to_path` or something similar?
Now that I think of it, I forgot to mention in a reply to an earlier
patch in this series that `reset_head()` might be too generic a name to
be a global function...
Ciao,
