* Where first /a or /b sets 'mode in operation' until another is found
* once another is found, it applies to the file preceding the /a or /b
* In addition each filename can contain wildcards
* To make matters worse, the + may be in the same parameter (i.e. no
* whitespace) or with whitespace separating it
*
* ASCII mode on read == read and stop at first EOF
* ASCII mode on write == append EOF to destination
* Binary == copy as-is

* Design of this is to build up a list of files which will be copied into a
* list, then work through the list file by file.
* If no destination is specified, it defaults to the name of the first file in
* the list, but the current directory.
