Fix bdiff test failures on AIX.
The test fails when, in the call to calloc(), the number of elements (bn)
is 0. In that case, calloc() on AIX will return NULL, while the code expects
a valid heap pointer. Both results are permissible under C99, Unix98 etc.
Work around by ensuring that at least 1 element is requested.

On Windows, this had the side effect of causing raw_input() to emit trailing carriage
returns on it's returned strings. This was causing web authentication problems.

copy: handle rename internally
- add rename parameter
- don't collect copied list
- report "moving" rather than "copying"
- remove renamed files
- don't return copied list
- simplify callers
