Subject: [PATCH] More trivial dead code removal: in int_to_roman(), checking
 for "num == -1" is redundant after a check has already been made for "num <
 0". The "set" variable can also be removed, as it is now no longer used. Per
 checking with Karel, this is the right fix.

Per Coverity static analysis performed by EnterpriseDB.
