Wanted: a verbosity mode that would print the actual commands being run

[mgedmin]

Should also work with -n.

Ideas for the flag: -x (a la sh -x), -v -v (downside: what if I don't want the plain-text descriptions of what it wants to do, and just want the shell commands?)

Other considerations: I often want to see what backup commands would be executed without running them. The overwrite check hampers that. Maybe it should be turned off in -n mode? But maybe not?
