-C::
Detect copies as well as renames.
+--diff-filter=[ACDMRTUXB*]::
+ Select only files that are Added (`A`), Copied (`C`),
+ Deleted (`D`), Modified (`M`), Renamed (`R`), have their

+ Unknown (`X`), or have had their pairing Broken (`B`).
+ Any combination of the filter characters may be used.

DESCRIPTION
-----------
*not* matching the regex, just prepend a single exclamation mark in front
(see EXAMPLES).
+The type specifier can be either '--int' or '--bool', which will make
+'git-repo-config' ensure that the variable(s) are of the given type and
+convert the value to the canonical form (simple decimal number for int,
+a "true" or "false" string for bool). If no type specifier is passed,
+no checks or transformations are performed on the value.
+
This command will fail if
. .git/config is invalid,

+From: Junio C Hamano <junkio@cox.net>
+Subject: Separating topic branches
+Abstract: In this article, JC describes how to separate topic branches.
+
+This text was originally a footnote to a discussion about the
+behaviour of the git diff commands.
+
+Often I find myself doing that [running diff against something other
+than HEAD] while rewriting messy development history. For example, I
+start doing some work without knowing exactly where it leads, and end
+up with a history like this:
+
+ "master"
+ o---o
+ \ "topic"
+ o---o---o---o---o---o
+
+At this point, "topic" contains something I know I want, but it
+contains two concepts that turned out to be completely independent.
+And often, one topic component is larger than the other. It may
+contain more than two topics.
+
+In order to rewrite this mess to be more manageable, I would first do
+"diff master..topic", to extract the changes into a single patch, start
+picking pieces from it to get logically self-contained units, and
+start building on top of "master":
+
+ $ git diff master..topic >P.diff
+ $ git checkout -b topicA master
+ ... pick and apply pieces from P.diff to build
+ ... commits on topicA branch.
+
+ o---o---o
+ / "topicA"
+ o---o"master"
+ \ "topic"
+ o---o---o---o---o---o
+
+Before doing each commit on "topicA" HEAD, I run "diff HEAD"
+before update-index the affected paths, or "diff --cached HEAD"
+after. Also I would run "diff --cached master" to make sure
+that the changes are only the ones related to "topicA". Usually
+I do this for smaller topics first.
+
+After that, I'd do the remainder of the original "topic", but
+for that, I do not start from the patchfile I extracted by
+comparing "master" and "topic" I used initially. Still on
+"topicA", I extract "diff topic", and use it to rebuild the
+other topic:
+
+ $ git diff -R topic >P.diff ;# --cached also would work fine
+ $ git checkout -b topicB master
+ ... pick and apply pieces from P.diff to build
+ ... commits on topicB branch.
+
+ "topicB"
+ o---o---o---o---o
+ /
+ /o---o---o
+ |/ "topicA"
+ o---o"master"
+ \ "topic"
+ o---o---o---o---o---o
+
+After I am done, I'd try a pretend-merge between "topicA" and
+"topicB" in order to make sure I have not missed anything:
+
+ $ git pull . topicA ;# merge it into current "topicB"
+ $ git diff topic
+ "topicB"
+ o---o---o---o---o---* (pretend merge)
+ / /
+ /o---o---o----------'
+ |/ "topicA"
+ o---o"master"
+ \ "topic"
+ o---o---o---o---o---o
+
+The last diff better not to show anything other than cleanups
+for crufts. Then I can finally clean things up:
+
+ $ git branch -D topic
+ $ git reset --hard HEAD^ ;# nuke pretend merge
+
+ "topicB"
+ o---o---o---o---o
+ /
+ /o---o---o
+ |/ "topicA"
+ o---o"master"
+
