When cloning from something (that is not yet known as an entity that we must go over the network), we do an equivalent of "test -f" (for bundles) and "test -d" (for local repositories), and I think the use of "does it refer to a local file" here matches it as a precedent. I do find it sloppy that the check uses file_name_is_absolute() that only checks the shape of the string, without seeing if it actually exists and is an executable file, though. Thanks.
