As modifyhtm.txt contains:

s//<font><\/font><\/BLOCKQUOTE>/

the reason for the error message is obvious.  The // refers to a
previously-compiled RE and there isn't one.  This is an error in
your script, not sed 4.0.1-1 and should also give the same error
message with sed 3.02-1.

As Randall says using / separators in s commands when slashes
are part of the RE is tricky.  You can use pretty much any
separator other than a backslash.
