Often, when user uses bit more complex syntax with xargs (or find -exec, for
that matter) the command spectacularly fails, and they dont know why. It
would be beneficial to be able to mock run a command - just print what is to be
run, so user knows what exactly is passed to the program, so they could
adjust/correct their command to do what they intended. It is specially
important when rm(1) is involved, as it can do real damage. Didnt know how to
call it but, you can figure out more accurate, or better name for it.
