convert_and_check_filename() checks after that already, mostly. For
TAP tests I am not sure that this would help much though as all the
nodes of a given test use the same root path for their data folders,
so you cannot just use "../hoge/" as location. We already generate a
warning when a tablespace is in a data folder, as this causes issues
with recursion lookups of base backups. What do you mean in this
case? Forbidding the behavior?
