It could be:
a) The minimum commit unit for both VSS and SVN is a file. That's the
smallest object you can actually version. (Well, technically a
versioned property is the smallest unit, but you still have to attach
the property to a file/dir.
Or it could be:
b) In the old days, many versioning systems would store binary files as
whole files. Nowadays they store deltas for both text and binary files.
From what I can google, it appears that VSS stores just the delta for
both text and binary files. Subversion uses deltas for both also.
"minimum commit unit" isn't a common metric that I'm familiar with.
Plus, I think the "minimum commit unit" metric listed on the site is not
useful and/or accurate. I would ignore the "minimum commit unit".
