Yeah, that sounds reasonable. Please document the new functions in Documentation/technical/api-strbuf.txt. Personally I would also advocate a docstring in the header file, but obviously that preference is the exception rather than the rule in the git project :-( Will do. I need to document the metapack functions, too, so I was thinking about experimenting with some inline documentation systems. -Peff -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

That would be great; it would make future API documentation much easier and therefore (hopefully) more common.
