[Support][CommandLine] Display subcommands in help when there are less than 3 

subcommands

This commit fixes a bug where the help output doesn't display subcommands when
a tool has less than 3 subcommands.

This change doesn't include a corresponding unittest as there is no viable way
to provide a unittest for it.
