Description

After issue #4227 is fixed, duplicate targets within the same svn:externals prop
are detected.

This issue is about detecting duplicate targets defined anywhere within the
bounds of the current WC. (Notably not including definitions from other WCs
above the current WC root. That should be yet another separate issue.)

This cannot simply be implemented during local propset/propedit. During update,
new svn:externals definitions can come in that clash with local definitions.
Also a partial commit (likely from a mixed-rev WC) may create a state where
clashing svn:externals definitions end up in the repository. Furthermore, any
currently used repos may already contain duplicates. So the implementation of
this feature would have to be able to deal with the presence of duplicates, with
some form of conflict resolution. Perfect enforcement would probably be hard to
achieve.
