Re: [RFC PATCH 1/1] for-each-ref: add '--no-symbolic' option

Eric Freese [off-list ref] writes:

However, this still prints an empty line for each ref that does not match the
condition. This can be cleaned up by piping through `grep .`, but what would
you think of adding a new optional flag to git-for-each-ref to prevent it from
printing empty expanded format strings?

Offhand I do not think of a reason why anybody wants to give a
format that results in a total blank, so it might not even need to
be an optional behaviour, but certainly a new option that triggers
such a behaviour would be a safe thing to add.
