That is exactly what happens currently - everything from `#' up to the next
EOL is ignored.

No, I am against it. It will turn into a nightmare.

echo foo \
#
# ... 57 lines of comments
#
echo bar

How do you like it?
                                                                      and b)

It is not a continuation. It is simply removing of EOL no more no less (and so
it is documented). Yes, for all practical purposes it is the same as
continuation ...

But I just realised. In case of

echo foo \
# comment
bar

how do you want to indicate, that `bar' is not a comment? I mean

echo foo \
#comment \
bar

is the same as

echo foo #comment bar

that makes bar be happily ignored. The above change is trivial,  but gains you
nothing. Anything else, I agree, is too error prone.
