What canonicalizing actually means is that it yields a unique filename
for some file. That is its primary functioning; not converting slashes,
stripping dots, simplifying double-dots, making absolute, adding drive
letters, un-SUBST-ing, un-ASSIGN-ing, capitalizing, adding "x:/DEV/" for
devices and other weird things.

A canonicalizing function should be complete enough to help decide
whether two filenames refer to the same file.
