Daniel, Dao Quang Minh 9ca9222a81 speed up creation of args and msg for huge cmds ...

Whenever a command arguments is formed by a large linked list, repeatedly
appending to arguments and displayed messages took a long time because go will
have to allocate/copy a lot of times.

This speeds up the allocation by preallocate arrays of correct size for args
and msg
