    General help message cleanup · a89c33db
    Wolfgang Denk authored
    Many of the help messages were not really helpful; for example, many
    commands that take no arguments would not print a correct synopsis
    line, but "No additional help available." which is not exactly wrong,
    but not helpful either.
    Commit ``Make "usage" messages more helpful.'' changed this
    partially. But it also became clear that lots of "Usage" and "Help"
    messages (fields "usage" and "help" in struct cmd_tbl_s respective)
    were actually redundant.
    This patch cleans this up - for example:
    	=> help dtt
    	dtt - Digital Thermometer and Thermostat
    	dtt         - Read temperature from digital thermometer and thermostat.
    	=> help dtt
    	dtt - Read temperature from Digital Thermometer and Thermostat
