MudGuard:
I pretty sure you're right. I believe my problem came from the program I was using for off-line viewing (preview) of the HTML.
I tried to post a song with chords, in a >PRE< section, and because of some off-beat synchopation, I marked measures using a slash " / " to show where the lyric was offset relative to the chord stroke.
It probably would have been okay if I had posted it as written, but I decided to get clever and preview it first.
I had it set up in MickeySoft Word, and did a save-as html, and it looked okay.
Going back now, and looking at the html in what I posted, I see that for some reason, the line breaks that came immediately in front of a Word paragraph break " ¶ " AND a " / "were deleted (or partially deleted?).

In other words:
>br<¶/ got changed to ¶/ only.
Where the >br<¶ was followed by anything else, its seemed to come across okay.

I'm sure the breaks were there originally, since I put them in with a global replace operation.
Since the original blew up on me when I sent it, I had to do some retyping, which I did in Word doc view. Since coming back from html view to doc view hides the html, I didn't see what had happened then.

I've seen some rather bizarre behavior from the Word ¶ mark. Its a composite character where the file characters (multiple - approximating but not exactly a linefeed plus carriage return?) are different than the display character (what you see on screen if you select to show them).

I think this is a Word html converter problem, probably peculiar to the program I used on my machine and not something relating to html in general. Someday soon I'll have to look over my tool box and actually learn how to use what's in the html tools.
