After working with Peter offline, here is what we've come up
with. I'm quoting from an email Peter sent me:
"As far as I recall, I just did two things.
First do a Find and Replace to remove all the
<!--begin--> comments. I did that using EditPadPro, a
text editor.
That tool also allows regular expressions in its Search and
Replace function.
I created one that found many lines but it was not the right
expression so I manually removed what it missed. Since then I found
the correct expression is as below with a replace of nothing. Do
backup your work first as regular expressions can fix things in
seconds, and break them even quicker.

Text editors will only allow you to do this to one file at a
time.
PowerGrep will allow you to do the same thing across multiple
files.
I repeat, these tools are dangerous so make sure you have
backups."
I've used the find and replace tool in RH with the strings
above and it seems to work fairly well. I'll probably use FAR on
all the project files in a copy of my projects and hope I don't
blow anything up.
