Recognizing \r in a regex is something GNU sed will do, but other sed

invocations, use a single Perl script to split output into headers
and body.

  pack-objects: split implications of --all-progress from progress activation
  instaweb: restart server if already running
  prune-packed: only show progress when stderr is a tty

Conflicts:
	builtin-pack-objects.c

Currently the --all-progress flag is used to use force progress display
during the writing object phase even if output goes to stdout which is
primarily the case during a push operation.  This has the unfortunate
side effect of forcing progress display even if stderr is not a
terminal.

Let's introduce the --all-progress-implied argument which has the same
intent except for actually forcing the activation of any progress
display.  With this, progress display will be automatically inhibited
whenever stderr is not a terminal, or full progress display will be
included otherwise.  This should let people use 'git push' within a cron
job without filling their logs with useless percentage displays.

Running 'git instaweb' when an instaweb server is already running will
fail (at least when the port is the same) and overwrite the pid file
used to track the currently running server. This turns out to be
especially annoying when the user tries to stop the previously running
server with 'git instaweb --stop' and is instead greeted with an error
message because the pid file has been destroyed.

Instead of allowing a user to start two instaweb servers, stop the
currently running server first and then start the new one. This should
be fine because it was never really possible to start two instaweb
servers in the first place due to the pid file issue outlined above.

One test case used 'xargs test', which assumes that 'test' is available
as external program. At least on MinGW it is not.

Moreover, 'git format-patch' was invoked in a pipeline, but not as the
last command. Rewrite the test case to catch breakage in 'git format-patch'
as well.

In commit ad3f9a71 (Add '--bisect' revision machinery argument) the
'--bisect' option was added to easily pass bisection refs to
commands using the revision machinery.

So it is now shorter and safer to use the new '--bisect' revision
machinery option, than to compute the refs that we must pass.

This works around a bug in curl versions up to 7.19.4, where disabling the
CURLOPT_NOBODY option sets the internal state incorrectly considering that
CURLOPT_PUT was enabled earlier.

The bug is discussed at http://curl.haxx.se/bug/view.cgi?id=2727981 and is
corrected in the latest version of curl in CVS.

This bug usually has no impact on git, but may surface if using multi-pass
authentication methods.

Add a new helper function, strbuf_add_indented_text(), to indent text
without a width limit, and call it from strbuf_add_wrapped_text().  It
respects both indent (applied to the first line) and indent2 (applied to
the rest of the lines); indent2 was ignored by the indent-only path of
strbuf_add_wrapped_text() before the patch.

Two simple test cases are added, one exercising strbuf_add_wrapped_text()
and the other strbuf_add_indented_text().

In the Table of Contents, there is a notable inconsistency:
first there is "GIT Glossary", followed by "Git Quick Reference"
on the very next line.

Running "grep -c" on user-manual.txt, I find 780 occurrrences of
"git", 37 occurrences of "Git", and 9 occurrences of "GIT".
In general, "git" is the preferred spelling, except at the
beginning of a sentence.

Therefore, change "GIT Glossary" to "Git Glossary" for consistency
with the rest of the document.

Looking at the other eight occurrences of "GIT" I found one other
occurrence that should be changed:

* The mention of "StGIT". Looking at the web pages for "Stacked Git"
  at http://www.procode.org/stgit, I only saw the spelling "StGit",
  except in http://wiki.procode.org/cgi-bin/wiki.cgi/StGIT_Tutorial,
  but that page was last updated in 2006.

The other seven occurrences should not be changed:

* Three occurrences were in the output of 'git show-branch' run
  on the git.git repository.

* One occurrence was in the output of 'git cat-file'.

* One occurrence was as part of the file name "GIT-VERSION-GEN".

* Two occurrences were in comments in scripts quoted in a description
  of Tony Luck's workflow.

The usage messages for some commands (such as 'git diff-tree')
are truncated because they don't fit in a fixed buffer of
1024 bytes.

It would be tempting to eliminate the buffer and the problem once
and for all by doing the output in three steps, but doing so could
(according to commit d048a96e) increase the likelyhood of messing
up the display.

So we just increase the size of the buffer.
