This is intentional. Read the NEWS file: User-visible changes in version 2.8: * The following diff options are still accepted, but are no longer documented. They may be withdrawn in future releases. -h (omit; it has no effect) -H (use --speed-large-files instead) -L (use --label instead) -P (use --unidirectional-new-file instead) --inhibit-hunk-merge (omit; it has no effect) > > Hi, > > as a further followup here: -L is used by "svn diff".

'svn diff' should be patched to use --label rather than -L. This is because a future version of diff might be taught to treat -HLP in the same manner as other recursive programs, such as chown, where -L affects how symlinks are treated during recursion. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
