--- Comment #5 from Benson Muite benson_muite@emailplus.org --- For utf8.h and utf8.c the notice is in the Copying file: https://github.com/github/cmark-gfm/blob/master/COPYING#L78
Maybe it is best to suggest retaining copyright notices at the top of each file derived from other sources?
Can package houdini separately, would need to update it to a shared library.
buffer.c and buffer.h were added in commit afeecf4f262b74270368ef8a70c582ea9d5a18e8 in libgit2 https://github.com/libgit2/libgit2 by vmg author of houdini so expect relicensing of these is ok.
Cannot find chunk.h in the libgit2 history
It was added to cmark-gfm by vmg: https://github.com/github/cmark-gfm/commit/460d46c62b0675f2fab6f103bb9f0d185...
