Check for unsaved buffers on commit

[gnbond]

I frequently get caught out doing a commit when I have last-minute changes unsaved in buffers. As currently implemented (v2.15.5) SVN does not warn about this and commits the on-disk version. Then I have to do an extra commit, and be mocked by my team (again).

I'd love it if svn could warn in this situation, as the Git plugin does (see e.g. this issue ) I've looked and cannot see any option that might enable this for svn.
