In fact, boost::filesystem::canonize already exists, albeit
deprecated. It doesn't appear to do anything, though, which confuses
me. boost::filesystem::normalize is too much, as it does the foo/..
=> . reduction, which is unsafe.
I would like to see similar things return, though. I'd advocate a
clean() member function that does the foo/./bar => foo/bar reduction
and ensures that all relative paths start with ./ or ../, and a
non-member expand that removes all symlinks and ..s (which would
require that it have a root).
