Good. I've made such change, it's now raw.log.txt and repro.c.txt:
https://github.com/google/syzkaller/commit/afcb994770d7e0f4b88c623bec76fbdce57d3910

I've also mailed a change to appengine that supports *.c, *.log and
*.patch as text/plain extensions. There does not seem to be any major
objects to it, but it will probably take some time to be deployed in
prod. After that I will rename them back.
