citation line above or below body?

[Eric Abrahamsen]

When I reply to messages and cite the original, point ends up below the
citation line. This leads to weird threads, where my text ends up right
below the "so-and-so wrote:" line, and other people's mail programs
don't seem to do it that way. My message-citation-line-function is
currently set to message-insert-formatted-citation-line, and I know that
I could simply write my own citation function, but my question is: why
is it like this, and will I be breaking anything if I "fix" it?

Thanks,
Eric
