For a long time, this developer thought that Git's insistence that
pushing into the current branch is evil was completely merited.
Just for fun, the original patch tried to show people that Git is right
there, and that it causes more trouble than it does good when Git allows
you to try to update the working tree for fast-forwards, or to detach the
HEAD, depending on some config settings.
Surprisingly, the opposite was shown.
So here is the support for two new options you can give the config
variable receive.denyCurrentBranch:
'updateInstead':
Try to merge the working tree with the new tip of the branch
(which can lead to really horrible merge conflicts).
'detachInstead':
Detach the HEAD, thereby avoiding a disagreement between the
HEAD and the index (as well as the working tree), possibly
leaving the local user wondering how on earth her HEAD became
so detached.

The test intends to rebase a branchy history onto a later commit, but it
forgot to reset HEAD back to an earlier commit before it set up the side
branches. In the end, every "rebased" commit was only a fast-forward and
the 'rebase -p' did not change the commit graph at all. Insert the missing
checkout that moves to an earlier commit.

Commit 875b91b (diff --no-index: use strbuf for temporary pathnames,
2012-04-25) introduced a regression when using diff --no-index with
directories. When iterating through a directory, the switch to strbuf
from heap-allocated char arrays caused paths to form like 'dir/file1',
'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected.
Avoid this by resetting the paths variables to their original length
before each iteration.

commit: refactor option parsing
In abe1998 ("git checkout -b: allow switching out of an unborn
branch"), a code-path overly-optimisticly assumed that a
branch-name was specified. This is not always the case, and as
a result a NULL-pointer was attempted printed to .git/HEAD.
This could lead to at least two different failure modes:
1) vsnprintf formated the NULL-string as something useful (e.g
"(null)")
2) vsnprintf crashed
Neither were very convenient for formatting a new HEAD-reference.
To fix this, reintroduce some strictness so we only take this
new codepath if a banch-name was specified.

This puts delta resolving on each base on a separate thread, one base

When we are showing reflog selectors during a walk, we infer
from context whether the user wanted to see the index in
each selector, or the reflog date. The current rules are:
1. if the user asked for an explicit date format in the
output, show the date
2. if the user asked for ref@{now}, show the date
3. if neither is true, show the index
However, if we see "ref@{0}", that should be a strong clue
that the user wants to see the counted version. In fact, it
should be much stronger than the date format in (1). The
user may have been setting the date format to use in another
part of the output (e.g., in --format="%gd (%ad)", they may
have wanted to influence the author date).
This patch flips the rules to:
1. if the user asked for ref@{0}, always show the index
2. if the user asked for ref@{now}, always show the date
3. otherwise, we have just "ref"; show them counted by
default, but respect the presence of "--date" as a clue
that the user wanted them date-based

When we show a reflog selector (e.g., via "git log -g"), we
perform some DWIM magic: while we normally show the entry's
index (e.g., HEAD@{1}), if the user has given us a date
with "--date", then we show a date-based select (e.g.,
HEAD@{yesterday}).
However, we don't want to trigger this magic if the
alternate date format we got was from the "log.date"
configuration; that is not sufficiently strong context for
us to invoke this particular magic. To fix this, commit
f4ea32f (improve reflog date/number heuristic, 2009-09-24)
introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.
Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.
This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

We already check that @{now} and "--date" cause the
displayed selector to use the date for both the multiline
and oneline formats. However, we miss several cases:
1. The --format=%gd selector is not tested at all.
2. We do not check how the log.date config interacts with the
"--date" magic (according to f4ea32f, it should not
impact the output).
Doing so reveals that the combination of both (log.date
combined with the %gd format) does not behave as expected.
