The briefs of the libmisc files named a topic, not the content of the file. Four shell briefs named the wrong command. The file main_blksync.c said "RM Shell Command Implementation". The files main_id.c, main_time.c and shellconfig.c named ls and debugrfs. Four string conversion sources named the conversion, for example "Convert String to Unsigned Long". Write every brief in the style of the tree. A source brief starts with "This source file contains". A command brief names the command the file provides. A header brief starts with "This header file provides". Put @file, @ingroup and @brief in this order in every block. Updates #5717.
