Log Message:
Readd optimization last night.  Problems earlier were partially due to the
arguments names on one function being swapped (by a previous author).

Do not do any duplicate suppression when a source list is created.  Instead:
* OP_MADE protects against trying to make the source multiple times.
* A new OP_MARK flag is introduced to suppress duplicates while expanding
  the .ALLSRC variable and .USE targets.
This turns the O(n^2) insertion into O(n) in most cases.

This is tested with a `make build' and some special test cases.
