Description

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

Only one entry per path should be allowed.

Suggestion: Implement a commit check which issues a warning if multiple entries
are found.
