Agreed. I'd rather make the definition "Can users, after a rename has 
taken place, follow the history of the file-contents across renames?". 
Mainly because this is clearly unambiguous, doesn't involve 
implementation details and only weighs what really counts: User-visible 
capabilities.

IMNSHO, I'd rather have all the features in the list be along the lines 
of "Can users/admins/random-boon do X?" and instead of "yes/no" list the 
number of commands/the amount of time required to achieve the desired 
effect. This would set a clear limit and put most terminology issues out 
of the way.

Yup. Any fast-growing SCM can clearly be said to be "extensible", 
otherwise it wouldn't be extended ;-)

This one just needs to go. Could possibly be replaced with "Has 
tutorial/documentation online" or some such. No SCM is really intuitive 
to users that haven't experienced any of them before, so the only thing 
that really matters is how much documentation one can find online and 
how up-to-date it is.
