The layout within the manuals was chosen entirely for clarity,
I imagine. Except within literal strings, Stata is indifferent
to the precise spacing between elements of a command. That is, you
can use one, two or more spaces according to choice.
Indeed in some cases at least you can even omit
spaces between elements, although I wouldn't recommend it.
In part, this issue was addressed recently by Bill Dupont and several
people commented. In essence, there is not a way to do this
within the command window short of inserting lots of spaces yourself
in the obvious but slow way,
but it is easier to do it within Stata's do file editor or within
your own favourite text editor in preparing do files.
It is clearly most helpful when learning the syntax. At the other
extreme, there are plenty of arguments favouring setting and
following definite conventions for Stata programs intended to be
durable, as have often been rehearsed.
