        No it doesn't.  Calling error() with an initial argument of 1 makes it
        call exit(), which terminates the process and frees *all* the memory, so
        there's no leak.
I almost put a note about that in the email, but I decided not to - my
mistake.

I think the addition of the final free() fixes a real leak.  (owd comes from
xgetwd(), and xgetwd()'s return value needs to be free()'d.)

The free()'s before the calls to error() bring up a style issue.  If I'm
debugging a program, I want it to release all memory before it exit()'s so
I can see what's leaked, even if I'm exiting on an error.  If cvs
doesn't get coded that way, my apologies for not noticing and cleaning up
too much :-)
