Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use SDL_ prefixed versions of C library functions. FIXME: Change #include <stdlib.h> to #include "SDL_stdlib.h" Change #include <string.h> to #include "SDL_string.h" Make sure nothing else broke because of this...
