+message:
+
+From: Nit Picker <nit.picker@example.net>
+Subject: foo is too old
+Message-Id: <nitpicker.12121212@example.net>
+
+Hopefully this would fix the problem stated there.
+
+
+I have included an extra blank line above, but it does not have to be
+stripped away here, along with the               		   
+whitespaces at the end of the above line.  They are expected to be squashed
+when the message is made into a commit log by stripspace,
+Also, there are three blank lines after this paragraph,
+two truly blank and another full of spaces in between.
+
+            
+
+Hope this helps.

+
+The git-cvsimport-script had a copule of small bugs that prevented me
+from importing a big CVS repository.
+
+The first was that it didn't handle removed files with a multi-digit
+primary revision number.
+
+The second was that it was asking the CVS server for "F" messages,
+although they were not handled.
+
+I also updated the documentation for that script to correspond to
+actual flags.

+textlive-* исправлены на texlive-*
+docutils заменён на python-docutils
+
+Действительно, оказалось, что rest2web вытягивает за собой
+python-docutils. В то время как сам rest2web не нужен.

+Subject: [PATCH] BLAH ONE

+In real life, we will see a discussion that inspired this patch
+discussing related and unrelated things around >8 scissors mark
+in this part of the message.
+
+Subject: [PATCH] BLAH TWO
+
+And then we will see the scissors.
+
+ This line is not a scissors mark -- >8 -- but talks about it.

+Subject: [PATCH] Teach mailinfo to ignore everything before -- >8 -- mark
+From: Junio C Hamano <gitster@pobox.com>
