added tests for newly enabled syntax

for --patch-from origin
and --filelist list

Also : removed some constrained syntax tests,
as the new argument parsing syntax is more permissive.

For example :
    zstd file -of dest
used to be disallowed.

It's now allowed, and understood as:
    zstd file -o dest -f
