That's a good idea, thanks! I've pushed a respective change to master.

However, the cache doesn't keep its own version, it uses just the Tramp
version for check. Using an own cache version is error-prone, there are
good chances to forget to change it when needed. At least *I* would
forget it always, as far as I know me.
