rG02f394281fd6: find: Fix -printf
Summary

Each -printf invocation created a memstream, then freed the underlying
buffer without closing the stream, resulting in a segfault on exit
when libc tried to flush all the streams.

While here, simplify the implementation of %h.

We should also try to figure out a way to call escape() only once.

This looks good. It matches what I have, plus fixes 'h'. So go ahead and test/commit it.
