The 1.6 client used to do that in some circumstances:

$ svn mkdir wc/A wc/A/B
$ svn revert wc/A
svn: Try 'svn revert --depth infinity' instead?
svn: Unable to lock 'wc/A/B'

In 1.7 the behaviour has changed, probably inadvertently. The locks
and the revert are now recurisive.

Another behaviour change. If wc/A/B is in the repository:

$ svn cp wc/A wc/C
$ svn revert wc/C/B

In 1.6 the revert does nothing, and produces no message. In 1.7 we

$ svn revert wc/X/B
Reverted 'wc/X/B'
$ svn st wc
A + wc/X
? wc/X/B

which is an invalid wc state.
