As far as I can tell, you can only turn off the behavior by
running in POSIX mode, which disables a lot of other Bash-specific
functionality.  Personally, I'm unwilling to do that.  I think I'd
like to see a "set -o" setting that disables just this feature.

You can *avoid* it by being careful not to put literal '~' characters
in $PATH (specifically at the beginning of any element of $PATH).
That's what I do (unintentionally before now, deliberately now that
I know about it.)
