Since 0e987a1 (am, rebase: teach quiet option, 2009-06-16), git-am
supported the --quiet option and GIT_QUIET environment variable, and
when told to be quiet, would only speak on failure. Re-implement this by
introducing the say() function, which works like fprintf_ln(), but would
only write to the stream when state->quiet is false.
