[PATCH v2 0/2] branch, for-each-ref: add option to omit empty lines

Changes since v1:

 - Improved commit message in 1/2,
 - Stopped considering flag combinations as an error, which greatly
   simplified the logic,
 - Improved weird test file generation,
 - Removed short option and renamed long option,
 - Changed conditions to check the string length before the flag, which
   imo. reads better.
