I like --no-clobber, particularly since it is similar to the bash (and
tcsh) noclobber shell option.

Seems reasonable to me.

The formatting is not very consistent here (are these full sentences, with
capitalization, periods, and two spaces, or just phrases?)

Does this actually do the right thing, or does it only prevent overwrites
at spots where, without arguments, a prompt would be issued? In other
words, is this particular implementation reinventing the same problems as
the deprecated --reply=no?
