No, it most certainly does not. SCCS stores all of the versions in an
interleaved form, something like:
#inserted in revision 1:
line 1
line 2
#inserted in revision 2:
line 2a
line 2b
#end revision 2
line 3
line 4
#removed in revision 3:
line 5
line 6
#end revision 3
line 7
line 8
line 9
#end revision 1
So, *no* version is stored ad verbatim, there are no "diffs" per se, and
it takes almost exactly the same time to retrieve any revision.
