gtkimhtml.c treats the first line of the message specially, and the previously
introduced changes caused problems with displaying conversation logs when saved
in HTML, exactly due to changing where the newlines are stored inside the file.
I believe this change brings the best of both worlds by changing the significant
part of the HTML markup so the validator is happy, and keeping the stuff that
gtkimhtml.c needs in the first line.
