I thought about a change like this, too. But I recall that this area has been 
changed several times. One thread I found here:

http://thread.gmane.org/gmane.comp.version-control.git/62472

See also the commit message of 77cb17e940, which introduces exec_cmd.*.

But probably the points raised there are already moot, and your change is 
good.
