;;; Commentary:
;; Magit is an interface to the version control system Git,
;; implemented as an Emacs package. Magit aspires to be a complete
;; Git porcelain. While we cannot (yet) claim, that Magit wraps and
;; improves upon each and every Git command, it is complete enough to
;; allow even experienced Git users to perform almost all of their
;; daily version control tasks directly from within Emacs. While many
;; fine Git clients exist, only Magit and Git itself deserve to be
;; called porcelains.

When a new branch is created, Magit offers the branch, commit, or
stash as the default starting point of the new branch. If there
is no such thing at point, then it falls back to offer the
current branch as starting-point. The user may then accept that
default or pick something else.
If the chosen starting-point is a branch, then it may also be set
as the upstream of the new branch, depending on the value of the
Git variable `branch.autoSetupMerge'. By default this is done
for remote branches, but not for local branches.
You might prefer to always use some remote branch as upstream.
If the chosen starting-point is (1) a local branch, (2) whose
name is a member of the value of this option, (3) the upstream of
that local branch is a remote branch with the same name, and (4)
that remote branch can be fast-forwarded to the local branch,
then the chosen branch is used as starting-point, but its own
upstream is used as the upstream of the new branch.
Assuming the chosen branch matches these conditions you would end
up with with e.g.:
feature --upstream--> origin/master
instead of
feature --upstream--> master --upstream--> origin/master
Which you prefer is a matter of personal preference. If you do
prefer the former, then you should add branches such as \"master\",
\"next\", and \"maint\" to the value of this options."

The command `magit-pop-revision-stack' inserts a representation
of the revision last pushed to the `magit-revision-stack' into
the current buffer. It inserts text at point and/or near the end
of the buffer, and removes the consumed revision from the stack.
The entries on the stack have the format (HASH TOPLEVEL) and this
option has the format (POINT-FORMAT EOB-FORMAT INDEX-REGEXP), all
of which may be nil or a string (though either one of EOB-FORMAT
or POINT-FORMAT should be a string, and if INDEX-REGEXP is
non-nil, then the two formats should be too).
First INDEX-REGEXP is used to find the previously inserted entry,
by searching backward from point. The first submatch must match
the index number. That number is incremented by one, and becomes
the index number of the entry to be inserted. If you don't want
to number the inserted revisions, then use nil for INDEX-REGEXP.
If INDEX-REGEXP is non-nil then both POINT-FORMAT and EOB-FORMAT
should contain \"%N\", which is replaced with the number that was
determined in the previous step.
Both formats, if non-nil and after removing %N, are then expanded
using `git show --format=FORMAT ...' inside TOPLEVEL.
The expansion of POINT-FORMAT is inserted at point, and the
expansion of EOB-FORMAT is inserted at the end of the buffer (if
the buffer ends with a comment, then it is inserted right before
that)."

When reading the revision from the minibuffer, then it might not
be possible to guess the correct repository. When this command
is called inside a repository (e.g. while composing a commit
