Subject: [PATCH] Fix seqset iterator when it ends in a comma
If the seqset ended with a comma, the substr_end marker would be just
before the trailing nul. In the next call, the loop to skip the
marker would iterate right past the end of string too.
The fix is simple: place the substr_end marker and skip past it
immediately.
