Description

Split off from issue #4227.

When setting or modifying the svn:externals property, it is possible to specify
multiple entries for the same path.

Example:

svn propget svn:externals trunk

https://svn-server:8080/svn/multi/extfolder1 barf
https://svn-server:8080/svn/multi/extfolder2 barf

Only one entry per path ('barf') should be allowed.

Issue #4227 covers the warning during propset/propedit. This issue is about
warning about duplicates in svn:externals props coming in from the server during
checkout, update, merge.
