Maintaining cvs-fast-export is, frankly, a pain in the ass. Parts of the code I inherited are head-achingly opaque. CVS repositories are chronically prone to malformations that look like bugs in the tool and/or can’t be adapted to in any safe way. Its actual bugs are obscure and often difficult to fix – the experience is not unlike groping for razor-blades in the dark. But people expect cvs-fast-export to “just work” anyway and don’t know enough about what a Zeno’s tarpit the domain problem is to be properly grateful when it does.
Still I persevere. Somebody has to; the thought of vital code being trapped in CVS is pretty nervous-making if you know everything that can go wrong with it.
This release fixes a bug introduced by an incorrect optimization hack in 2014. It should only have affected you if you tried to use the -c option.
