I have committed Bert's patch, with the command modified to be "svn info
--viewspec", in http://svn.apache.org/r1826864
Let's see where it leads.
First I'd like to 'clean up' the formatting a bit to make it easier to
read, and add some tests.

We need to look at using the viewspec as input next. Semantically
speaking, these sorts of things:
* a way to check out a new WC to match the spec;
* a way to modify an existing WC to match the spec;
* a way to modify/checkout a WC of a *different* branch, to match the
spec except for its URLs (maybe switch URLs pointing inside this
'branch' or WC get adjusted as if they are relative, and other switch
URLs stay absolute?);
