Description

The -getmerge shell command always write a local CRC file. It's prefixed with a '.', so it's a hidden file and often goes unnoticed. This behavior differs from -get, which skips writing the CRC file by default, but allows the user to opt in to writing a CRC file by passing the -crc argument. This issue proposes adding support to -getmerge to skip writing the CRC file.
