naming in repos_diff.c

Hi Arfrever, Stsp,

would you guys be fine with the attached patch? Calling that thing
"diff_editor" got me confused there for a while.

Furthermore, could you explain why you chuck the local svnpatch_* functions
into an (also local) svn_delta_editor_t in the first place? It makes much
more sense to me to just call them directly without the editor struct.

Thanks,
~Neels
