I have some external mydiff3.exe, working with text and binary files.
My svn command line is
svn.exe update my_work_copy_path --diff3-cmd mydiff3.exe
This work well for text files (svn call mydiff3.exe for each conflicted files through update process), but for binary files svn skip the mydiff3.exe and show the internal commandline menu.
How to tell to svn to accept --diff3-cmd mydiff3.exe for binary files?
RTFM (diff3-cmd and External Tools from svn red-book) doesn't help.
UPD: There is a mention that the behavior depends on mime-type - but it is not clear where to configure it.
