I observe that almost the whole body of svn_wc__get_info() is a
duplicate of the callback function above it, info_found_node_callback().

For a start, we can replace the body by a call to that. (I'm testing
that now.)

As a follow-up, it looks like the code here is a work-around for
svn_wc__node_walk_children() not providing the behaviour that we want
from it. This appears to indicate that svn_wc__node_walk_children()
doesn't call the callback function if the target node is non-present and
has a tree conflict, whereas it does call the callback function for any
child node it encounters that is non-present and has a tree conflict.
We should at least document what it does exactly, and at best improve it
and test it.
