small feature request: when checkout/update print out svn:external addresses

Hi

not long ago we have made some reorganization in repository, but forgot to make svn:external relative instead of absolute
and I was really confused when build errors surprizingly appeared in an unchanged tags

so I think it would be useful to print out external addresses too
eg not just
"Fetching external item into '...'"
but
"Fetching external item from '...' into '...'"

it will allow to recognize such errors easily
