[PATCH] change of variable name: 'diff_cmd_baton' to 'dwi' in subversion/libsvn_client/diff.c

Whilst rooting around, I saw that the local variable 'diff_cmd_baton'
was changed to the type diff_writer_into_t and in most other placed had
the name 'dwi'.

I changed all the local instances in subversion/libsvn_client/diff.c to
match the new naming scheme.
