Sure it can.  If you're committing to branch X, and the current tree has
a whole lot of commits above that, then it should do the only thing you
can do with SVN.

Which is write a squash commit, and set the "svn:merge" and/or
"svk:merge" properties to represent what happened.

If you really want one, use git commit-tree directly.
