Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options. The messages
are better formatted and printed to te same place that hb-shape output is
directed to. Previously they were written to stderr.
Fixes https://github.com/behdad/harfbuzz/issues/506
Currently just announces lookup applications. Message-API *will* change.
hb-shape / hb-view are updated to print-out messages to stder if --debug
is specified.
