Oh, I thought it was so simple. :) Anyway, vfs_canon is modified to
first canonicalize without tilde expansion. If this expanded file
exists (according to the vfs's stat function), this name is returned.
Otherwise, vfs_canon will simply canonicalize *with* tilde expansion
and return the result.

To accomplish this it was necessary to create a new function
vfs_canon_internal that can canonicalize either with tilde expansion
or without.

The drawback is that vfs_canon in worst case takes twice as long,
plus the time for the vfs stat call.
