This patch does proper quoting, and uses "env" to be compatible with
tcsh.  As a side benefit, I believe the code is a lot cleaner to read.

[jc: I am accepting this not because I necessarily agree with the
 quoting approach taken by it, but because (1) the code is only used
 by ssh-fetch/ssh-upload pair which I do not care much about (if you
 have ssh account on the remote end you should be using git-send-pack
 git-fetch-pack pair over ssh anyway), and (2) HPA is one of the more
 important customers belonging to the Linux kernel community and I
 want to help his workflow -- which includes not wasting his time by
 asking him to switch to git-send-pack/git-fetch-pack pair, nor to use
 a better shell ;-).  I might not have taken this patch if it mucked
 with git_connect in connect.c in its current form.]

By default the curl library adds "Pragma: no-cache" header to all
requests, which disables caching by proxy servers.  However, most
files in a GIT repository are immutable, and caching them is safe and
could be useful.

This patch removes the "Pragma: no-cache" header from requests for all
files except the pack list (objects/info/packs) and references
(refs/*), which are really mutable and should not be cached.

The new flag '-d' lets you delete a branch.  For safety, it does not
lets you delete the branch you are currently on, nor a branch that
has been fully merged into your current branch.

The credit for the safety check idea goes to Daniel Barkalow.

An entry in the alternates file can name a directory relative to
the object store it describes.  A typical linux-2.6 maintainer
repository would have "../../../torvalds/linux-2.6.git/objects" there,
because the subsystem maintainer object store would live in

    /pub/scm/linux/kernel/git/$u/$system.git/objects/

and the object store of Linus tree is in

    /pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects/

This unfortunately is different from GIT_ALTERNATE_OBJECT_DIRECTORIES
which is relative to the cwd of the running process, but there is no
way to make it consistent with the behaviour of the environment
variable.  The process typically is run in $system.git/ directory for
a naked repository, or one level up for a repository with a working
tree, so we just define it to be relative to the objects/ directory
to be different from either ;-).

Later, the dumb transport could be updated to read from info/alternates
and make requests for the repository the repository borrows from.

CDPATH has two problems:

 * It takes scripts to unexpected places (somebody had
   CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base
   took him to $HOME/.git when he said "clone foo bar" to clone a
   repository in "foo" which had "foo/.git").  CDPATH mechanism does
   not implicitly give "." at the beginning of CDPATH, which is
   the most irritating part.

 * The extra echo when it does its thing confuses scripts further.

Most of our scripts that use "cd" includes git-sh-setup so the problem
is primarily fixed there.  git-clone starts without a repository, and
it needs its own fix.

If you make a commit on a path, and then make the path
cache-dirty afterwards without changing its contents, 'git
checkout' to switch to another branch is prevented because
switching the branches done with 'read-tree -m -u $current
$next' detects that the path is cache-dirty, but it does not
bother noticing that the contents of the path has not been
actualy changed.

Since switching branches would involve checking out paths
different in the two branches, hence it is reasonably expensive
operation, we can afford to run update-index before running
read-tree to reduce this kind of false change from triggering
the check needlessly.

There are several undocumented dependencies in the .spec and in the
INSTALL files. The following is from Fedora, perhaps other RPM
distributions call the packages differently.

Also, the manpages aren't always installed gzipped.

Updates to git-core.spec.in file:
 - Some git scripts use Perl
 - gitk needs wish, which is part of TCL/Tk.
 - curl is used all over
 - Need the ssh program from openssh-clients

 - Mention wish

This allows any arbitrary flags to "grep", and knows about the few
special grep flags that take an argument too.

It also allows some flags for git-ls-files, although their usefulness
is questionable.

With this, something line

	git grep -w -1 pattern

works, without the script enumerating every possible flag.

[jc: this is the version Linus sent out after I showed him a
 barf-o-meter test version that avoids shell arrays.  He must
 have typed this version blindly, since he said:

    I'm not barfing, but that's probably because my brain just shut
    down and is desperately trying to gouge my eyes out with a spoon.

 I slightly fixed it to catch the remaining arguments meant to be
 given git-ls-files.]

Very convenient shorthand for

	git-ls-files [file-patterns] | xargs grep <pattern>

which I tend to do all the time.

Yes, it's trivial, but it's really nice. I can do

	git grep '\<some_variable\>' arch/i386 include/asm-i386

and it does exactly what you'd think it does. And since it just uses the
normal git-ls-files file patterns, you can do things like

	git grep something 'include/*.h'

and it will search all header files under the include/ subdirectory.

This should work around the compilation problem Johannes Schindelin

Quoting Linus:

    Any operating system where socklen_t is anything else than "int" is

    and I actually had to argue with them that it was fundamentally wrong:
    there is no other valid type than "int" that makes sense for it.
