Commands does not trim white spaces

[GlendaChong]

If a user types view-stall, it becomes an unknown command, though it is quite common for users to type spaces by accident. This causes inconvenience as many of the commands have the format A-B. And users always have to do an extra delete of space.

Team's Response

All our commands do not have any whitespace to make it clear for users that they do not need whitespaces for command words. If the user accidentally types a space, it is a typo on their part, just the same as if they misspelled a command word. As such, the error message already accurately reflects that it is an unknown command, and the user would know to fix it.
