This is not a bug. The substitution exists to deal with
subtle formatting characteristics of browsers. Although
it looks redundant, it generates output that properly
reflects the formatting of the orginal data
I don't know which browsers you have in mind, but according to my tests,
Mozilla, NS7 and Opera seem not to be affected, while rendering by MSIE
and NS4 does *not* reflect the original properly: All blank lines are
ignored.
I use Galeon, which uses the Mozilla Gecko rendering engine.
Without the substitution, some line breaks are "lost" due to the
inherent rendering characteristics of the browser (i.e. line breaks
after a start (<pre>) tag and before a close (<pre>) tag are typically
ignored).
At the end of this message is the test mesasge text I test against.
I used it for testing the flowed and fanyquote. When testing for
fancyquote, I use the following resource setting to disable flowed
processing since the message headers of the test message
specify flowed formatting:
<MIMEArgs>
m2h_text_plain::filter; fancyquote disableflowed maxwidth=80
</MIMEArgs>
If you comment out, or delete, the s/// operator, you will see that
some line breaks get "lost", mainly between two quoted chunks. The
difference may be subtle and not apparent with most mail messages.
Here is the test data (ignore the "flowed" comments in the text
when testing fancyquote since they only indicate what should happen
if flowed formatting is used):

This text should not be flowed since there
is no extra spaces at the end of the lines
in this paragraph. However we will just have
to see if the filter does the correct thing.
This row ends with [^ ]\r\n, and is converted to a fixed font.
This row ends with [^ ]\r\n, and is converted to a fixed font.
This row ends with [^ ]\r\n, and is converted to a fixed font.
But the rows below should be displayed in a fixed
font, since it is a separate para and lines end with [^ ]\r\n:
for (split (/[&;]/, $in)) {
($name, $value) = split(/=/);
$value =~ s/%(..)/pack("c",hex($1))/ge;
$in{$name} = $value;
}
Typically, when you post a code fragment, you want it to be viewed
with a fixed font, don't you?
This is another flowed paragraph. I want to see if a proper line
break exists between this paragraph and the preceding one. Also this
para has complete nothing to say.
Here is another flowed. This one has a few line breaks before it.
Do they get compressed or are they presevered. Well, we'll just have to
find out.
This is a short paragraph.
Here is some quoted text
that should be flowed.
Here is another short paragraph.
This is a really long line. This is a really long line. This is a really long

Since this paragraph EOLs are just newlines.
