git log -p:

-    noconfigdirs="$noconfigdirs gdb sim"
+    noconfigdirs="$noconfigdirs sim"

git annotate:

git show 34dd72a9

What's wrong with it?  And if I search which commit changed it:
	git log -p -Sgdb configure.ac

Still there should be stored + shown the associated mail which completely
misses here and which is stored there by GIT.

Currently I have to always look up the associated mails with each CVS commit
to have the reasons and background of each patch; it is really a lose of
engineering time looking up all the mails by hand I have to do with CVS:
	http://pkgs.fedoraproject.org/gitweb/?p=gdb.git;a=blob_plain;f=gdb-upstream.patch;hb=f16

	etc.

When I was a newbie to GDB I would not see the reason why string "gdb" was
removed from variable "noconfigdirs".  I would like to find out the mail
submit/reasoning/approval.  I tried now but I failed to find the mail.

Contrary to it you can see the explanation of a commit in:
	http://git.kernel.org/?p=git/git.git;a=commit;h=d4e85a1afe0a3310a3c8336c2824775901cc27d7

It is true I would prefer URL / Message-ID for the mail thread, it is not
commonly there even with GIT.  There are some other patch management software
for such tracking.
