Changes for version 2.14

  • Patch push_subgraph() to correctly handle the case of an unnamed subgraph. The code was outputting 'subgraph "" {...}'. The extra "" are now suppressed. The code also handles the case of the name being undef. There are no doc changes because the docs described precisely what should have happened, thusly: So, without $name, 'subgraph {' is written to the output stream. With $name, 'subgraph "$name" {' is written to the output stream. Many thanx (again) to Larry Marso for reporting this, with sample code.
  • Add scripts/unnamed.sub.graph.pl.
