branch, for-each-ref, tag: add option to omit empty lines
If the given format string expands to the empty string, a newline is
still printed. This makes using the output linewise more tedious. For
example, git update-ref --stdin does not accept empty lines.
Add options to "git branch", "git for-each-ref", and "git tag" to
not print these empty lines. The default behavior remains the same.
