This is for the usual case where only one sequence is requested.
When more than one sequence is requested, the suggested name comes out
as ${projectId}-${sequenceList}.${extension}, where `sequenceList` is
the list of sequence numbers separated by semicolons, e.g.:
eq21203-37;38;39.html.
Closes #116.
