busybox. This shell is actually a derivative of the Debian 'dash'
shell (by Herbert Xu), which was created by porting the 'ash' shell

- Enable tab completion in shell.
+ This option causes the selected busybox shell to use busybox applets
+ in preference to executables in the PATH whenever possible. For
+ example, entering the command 'ifconfig' into the shell would cause
+ busybox to use the ifconfig busybox applet. Specifying the fully
+ qualified executable name, such as '/sbin/ifconfig' will still
+ execute the /sbin/ifconfig executable on the filesystem. This option
+ is generally used when creating a staticly linked version of busybox
+ for use as a rescue shell, in the event that you screw up your system.
-config CONFIG_FEATURE_COMMAND_USERNAME_COMPLETION
- bool "username completion"
