The most common situation where I see this is on mailing lists.  For anything 
except very slow lists, I usually sign up for the "digest" version, so I get 
the day's postings in a single message.  Most mailing list software just grabs 
the text/plain parts and appends them to the digest, without translating the 
character set.  Thus, the digest message will be marked as 7bit, but individual 
posts that started life as quoted-printable will still be filled with trailing 
= and embedded =20 and =3D symbols.  This is particularly annoying for 
programming lists where people post code samples, because "=" gets translated 
to "=3D".

The =20 is necessary because RFC822 allows mail transfer agents to strip 
trailing blanks from the ends of lines in a message body.  For word-wrapped 
text, that produces sub-optimal results.
