Yep, that was sloppy of me.  commit-tree has already been libified.

As long as the term "allocation" is defined clearly.  For example
(written in the modern syntax for conciseness):

	{
		xmalloc from main()
		Memcheck:Leak
		...
		fun:xmalloc
		fun:main
	}
	{
		xmalloc from built-in main
		Memcheck:Leak
		...
		fun:xmalloc
		fun:cmd_*
	}

Even better would be to exit() instead of returning from cmd_
functions.  Valgrind will not consider any memory that still has a
pointer to it at exit time as a leak.
