How to alter default behavior of svn commit?

I often want to commit a few files that I've edited, but not others.
So, I do something like:

    svn commit A B C

But if I've edited files A through Z, and I unintentionally type

    svn commit

I send all those files to the repository.

Here's my question: is it possible to somehow change the default
behavior of svn commit so that it will ONLY commit the files listed on
the command line?

TIA
