If you have code like this
{code}
some_fun() ->
ok.
usage() ->
S = <<"
multi-line
usage
string
">>,
io:put_chars(S)..
another_fun() ->
true.
{code}
then indenting the usage() function, and especially a region that includes this function, will mess up the carefully left-aligned (starting at column zero) help string.
