expand-file-name doesn't signal errors, and I don't think it would be
a good idea to have it start doing that.

file-name-absolute-p is not smart enough to handle this case with the
rigor we are discussing, so I don't think this aspect is important for
the purposes of this discussion.  The "/:" quoting was chosen because
it fools file-name-absolute-p, so the above is not surprising.
