Hello! Starting from Subversion 1.10, the command-line client automatically resolves tree conflicts using the recommended resolution option when it's available. An example of such recommended resolution is the "Move and merge" action that can be available for tree conflicts caused by renames.
The relevant links are: https://svn.apache.org/r1783500 https://svn.apache.org/viewvc/subversion/trunk/subversion/svn/conflict-callbacks.c?view=markup#l1801 TortoiseSVN commands currently have the "old" behavior where the user has to choose the conflict resolution option manually. I would like to propose a patch that makes the TortoiseSVN commands (merge, update, switch, resolve) automatically apply the recommended tree conflict resolution when it's available. With the patch, TortoiseSVN commands have the same behavior as the command-line client, with an improved user experience in multiple cases, especially when an operation such as merge causes multiple tree conflicts.

Automatically resolve tree conflicts using the recommended resolution option when it's available. The change applies to the TortoiseSVN Merge, Switch, Update and Resolve commands. Subversion behaves this way starting from version 1.10.
