This is a follow-up patch based on conversation from the thread: "[RFC
PATCH 1/1] for-each-ref: add '--no-symbolic' option"

I had proposed a `--no-symbolic` option to git-for-each-ref that would
filter out symbolic refs from the output. It was discovered that the
behavior was already possible using an `%(if)` atom, but with the small
caveat that empty lines would be output for each non-symbolic ref.

This patch changes the output behavior of git-for-each-ref such that it
only prints lines for refs for which the format string expands to a
non-empty string.

If this is deemed to be too disruptive of a change, a new command option
could be added to opt in to the new behavior.
