Bash Version: 5.1
Patch Level: 12
Release Status: release
Description:
I have noticed that ~0 expands to the same value ~CURRENTUSER
would expand to, instead of expanding to `~0' (i.e. not expanding).
~00, ~000, ~0000, etc have the same behaviour.
Is this intended? It does not seem to be documented.
