SVN comes with its own built-in "diff" utility that differs from usual
"diff" command.  Consequently, it does not understand the "-Naur"
option.  That is rather inconvenient.  I do agree.  When we moved GCC
to SVN, that was one of the "minor" inconveniences I found.

"Fortunately", people have been through that trouble before and
documented the "solution":

  http://gcc.gnu.org/wiki/SvnTricks

Look at the section "How can I get context diffs? How do I configure
an external diff tool?"

You don't need to have duplicate copies of Axiom before sending a
patch.  I suspect one would make more mistakes by hand-managing diffs
of copies than having widely-tested tools do it.

For those who uses SVK, I'll add a documentation later.
