OK, I'll try :)
For easier understanding I kept the wording from your reshuffled series.

[PATCH 1/6] add a test for git-send-email for non-threaded mails
[PATCH 2/6] send-email: fix non-threaded mails
[PATCH 3/6] doc/send-email: clarify the behavior of --in-reply-to with --no-thread
[PATCH 4/6] add a test for git-send-email for threaded mails without chain-reply-to
[PATCH 5/6] send-email: fix threaded mails without chain-reply-to
[PATCH 6/6] send-email: fix a typo in a comment

The first three patches apply to the tip of 'maint', which is currently at
94af7c3 (Documentation: git-send-mail can take rev-list arg to drive
format-patch, 2009-06-11).  The first one exposes breakage introduced by
3e0c4ff and then the second one fixes it.

The last three patches apply to the tip of 'master'. Patch 4/6 exposes
breakage introduced by 15da108, patch 5/6 fixes it.

Changes compared to 'pu':

 * adjusted the description of 2/6 to hopefully add less confusion
 * changed the order of 4/6 and 5/6 and applied 5/6 directly on top of 4/6,
   since the regression was immediately noticable
 * also change test_expect_failure to test_expect_success in 5/6 then
 * instead of in the former merge commit a6f8abc "Merge branch
   'mh/master-send-email-threaded-fix' into mh/master-send-email"
