[PATCH 1/3] command: do not allow abbreviated commands anymore

[Sascha Hauer]

abbreviated commands are derived from U-Boot and are only
partly useful. Noone expects from a shell to support this,
also we have tab completion. They also have some funny
side effects. For example we have a 'time' command. If this
command is not compiled in, the time command is interpreted
as an abbreviated version of the 'timeout' command. So remove
support for abbreviated commands and safe the binary space.
