Makes sense, but nothing being discussed here has to do with crossing
repository boundaries so far.

This behavior explicitly standardized in POSIX:
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html:
The special filename dot shall refer to the directory
specified byits predecessor. The special filename dot-dot
shall refer to the parent directory of its predecessor
directory. As a special case, in the root directory, dot-dot
may refer to the root directory itself.c
The same goes for "foo", "./foo", "./././././foo" etc.

Yes, offhand I don't know where we canonically document our behavior of
not crossing repo boundaries, or rather not going "up".
