I do see your point about not wanting to overwrite a file in the user's
wc when trying to add a new file that has already been committed to the
repository, and I agree that it is valid that this should be an error
condition, and should be brought to the attention of the user.

However, I am not sure that the state of the wc after this failure is
desirable. Even after removing the offending file, an update produces an
error of the form "File not found: transaction 'nn' etc".
There can be many instances of .svn/entries files that have the
"incomplete=true" flag, and there is the potential that only some of the
changes in the new revision have been applied before the error, the
remainder have not been applied.

What would be the recommended recovery action if the "already exists"
error occurred, in order to be sure of a known state of the wc?

Thanks for your help.
