If you copy, using cp, a file to itself, and the target and source files
differ in capitalization, then the content of the file is wiped out; it
becomes a file of 0-length. Example: "cp hilbert.c hilbert.C" trashes
file hilbert.c.
The Win95 "copy" command gives the error message "File cannot be
copied onto itself" in this situation (much preferable)
