Summary: codecs.readline sometimes removes newline chars

Initial Comment:
In Python 2.4.1 i observed a new bug in codecs.readline,
it seems that with certain inputs it removes newline
characters from the end of the line....

Probably related to bug #1076985 (Incorrect
behaviour of StreamReader.readline leads to crash)
and bug #1098990 codec readline() splits lines apart
(both with status closed) so I'm assigning this to Walter.

See the attached files that demonstrate the problem.
Reproduced with Python 2.4.1 on windows XP and on
Linux. The problem does not occur with Python 2.4.

(btw, it seems bug #1076985 was fixed in python 2.4.1,
but the other one (#1098990) not? )

Checked in a fix as:
Lib/codecs.py 1.42/1.43
Lib/test/test_codecs.py 1.22
Lib/codecs.py 1.35.2.6
Lib/test/test_codecs.py 1.15.2.4

Are you really sure, that the fix for #1098990 is not in
2.4.1? According to the tracker for #1098990 the fix was in
lib/codecs.py revision 1.35.2.2 and revision 1.35.2.3 is the
one that got the r241c1 tag, so the fix should be in 2.4.1.
