Some people don't like the fact that Subversion merges changes from others
with their own local working copy changes automatically on update.
Here's how to force those files into a conflicted state so you can merge manually at your convenience.
1. In TortoiseSVN->Settings->Subversion configuration file, click on the edit button.
2. Change the [helpers] section by adding diff-cmd = "C:\\false.bat" diff3-cmd = "C:\\false.bat" (note the double backslash)
3. Create the file C:\false.bat which contains two lines
4. @type %9@exit 1.
This effectively makes auto-merge fail every time, forcing the file into conflict.
The reason for the curious 'type %9' line is that the diff3-cmd sends the merged output to stdout.
Subversion then takes this and overwrites your local file with the merge results.
Adding this line avoids getting an empty local file.
