Part of the code is under GPL2 #480

Pointed out in code review is that buffer.h and buffer.c seem to be derived from Houdini buffer.h and Houdini buffer.c which are available under GPL2 with a linking exception and originally came from libgit2

buffer was added by @vmg who at the time was working for GitHub, where this code was developed. @vmg certified in https://github.com/commonmark/commonmark-spec/pull/269 that the license was correct.

By the way @vmg is also one of the libgit2 contributors. Hopefully @vmg can comment here to clarify things.

The PR in https://github.com/commonmark/commonmark-spec/pull/269 is the authoritative source for licensing information.

@vmg certifies by merging this PR that the license and copyright information are accurate.

I approved that PR and re-licensed the code under the same permissive license as the rest of cmark. There is no GPLv2 code in cmark because that would make the library useless.

Thanks. A related issue is the copyright notices on utf8.h and utf8.c
