This is a bug. I expected os.path.expandvars() to replace references non-set environment variables with nothing, but it leaves them as is. Work around it by letting base_dir = None be special and the default. It uses $srctree if set and the current directory otherwise. This has the following advantages: - It avoids having to reimplement a different version of os.path.expandvars() and special-casing "" to mean the current directory. - It means '$' can appear in paths. (Though it probably never will.) Maybe the expansion behavior could be removed too, but keep it for now to be backwards compatible.
