And I'm more and more of the opinion that relying on fixed-width
tabulated output in scripts is fragile at best. Or to turn this around,
you'll never get both user-readable and fixed-format machine-readable
output at the same time; sooner or later one side must yield, and I
think it's more important that users see something they can understand..

That's why I suggested that every SVN command that produces console
output shoudl have an --xml version. (And I'm sure psvn would be
delighted if we had a --lisp version, too :-)
