0x0a is appended to attachments. pgnus 0.95 Bug?

[Mike Fabian <mike.fabian@it-mannesmann.de>]

When trying to send a *.tar.gz file as an attachment, it seems that
an additional 0x0a character is appended to the end of the file.

For testing I  did send the speedbar-0.8.1.tar.gz as  an attachment to
my own address and used

    `Gcc: nnfolder+archive:archive'

to get a  copy in my archive. When  the test mail returns to  me and I
save the attachment to  the file test4-speedbar-0.8.1.tar.gz, the file
seems to be corrupted:

    ~$ gzip --test --verbose test4-speedbar-0.8.1.tar.gz 
    test4-speedbar-0.8.1.tar.gz:	
    gzip: test4-speedbar-0.8.1.tar.gz: unexpected end of file
        
The original file was OK:

    ~$ gzip --test --verbose speedbar-0.8.1.tar.gz 
    speedbar-0.8.1.tar.gz:	 OK

comparing yields:

    ~$ cmp -l test4-speedbar-0.8.1.tar.gz speedbar-0.8.1.tar.gz
    cmp: EOF on speedbar-0.8.1.tar.gz

    ~$ ll test4-speedbar-0.8.1.tar.gz speedbar-0.8.1.tar.gz
    -rw-r--r--   1 0        Everyone    48086 Jul 29 13:34 speedbar-0.8.1.tar.gz
    -rw-r--r--   1 0        Everyone    48087 Jul 29 14:30 test4-speedbar-0.8.1.tar.gz


i.e. the  received attachment  is one byte  longer than  the original.
Looking at the two files with Emacs I find that the only difference is
the last  byte of test4-speedbar-0.8.1.tar.gz which has  the hex value
0x0a.   After removing  this  byte  diff says  it's  identical to  the
original and I can gunzip it.

The copy of the mail which was  Gcc'ed to my archive does not have the
problem of the  extra 0x0a byte. When I save  the attachment from this
copy,  no 0xa  is appended  and  the saved  file is  identical to  the
original.

Is this a bug or am I doing something wrong? I am using

(version)
"GNU Emacs 20.3.11b.1 (i386-*-nt4.0.1381)
 of Mon Jul 12 1999 on gridlock"
(gnus-version)
"Pterodactyl Gnus v0.95"
