I apologize for the spelling error in the subject of this thread.
I was told that this sentence actually states that lines inside a
(single) command argument cannot end in a line comment.
I initially thought that "Command Arguments" in this sentence means
the "section" that contains all the arguments in a command invocation,
as the wording implies that there may be multiple lines inside the
referred "Command Arguments".
However, a bracketed or a quoted argument can span several lines, so
the sentence means that one cannot have comments in a bracketed or
quoted argument (the grammar does not allow unescaped "#" inside an
unquoted argument, so I think the sentence does not refer to this
case).
Is this correct?
