At work we have a gforge setup that uses git. Now we coordinate who
does what so the following has never been done but if we both edit a
page.

1. You check the comments
2. Check the actual schematic page(s).
3. There is code out there for doing visual diff of them. (i would
love a git web plugin for this and preview)
4. You talk to the other user.

When you have multiple users working on the same project people
generally have to break off parts of the design. It is the only way to
coordinate anything. So the issue you are imagining is very rare for
schematics. PCB layout can get more hairy.
