Makefile: fix misdetection of relative pathnames
The installation rules wanted to differentiate between a template_dir that
is given as an absolute path (e.g. /usr/share/git-core/templates) and a
relative one (e.g. share/git-core/templates) but it was done by checking
if $(abspath $(template_dir)) and $(template_dir) yield the same string.
This was wrong in at least two ways.
* The user can give template_dir with a trailing slash from the command
line to invoke make or from the included config.mak. A directory path
ought to mean the same thing with or without such a trailing slash but
use of $(abspath) means an absolute path with a trailing slash fails
the test.
* Versions of GNU make older than 3.81 do not have $(abspath) to begin
with.
This changes the detection logic to see if the given path begins with a
slash.
This rewrites the example part of the bundle doucmentation to follow
the suggestion made by Junio during a recent discussion (gmane 108030).
Instead of just showing different ways to create and use bundles in a
disconnected fashion, the rewritten example first shows the simplest
"full cycle" of sneakernet workflow, and then introduces various
variations.
The words are mostly taken from Junio's outline. I only reformatted
them and proofread to make sure the end result flows naturally.

ordering of the hook call appears to have gone unnoticed, but since
git-cvsserver is supposed to emulate receive-pack, it stands to
reason that the hook should be run *after* the update. Since this
behavior is inconsistent with recieve-pack, users are either:
1) not using post-update hooks with git-cvsserver;
2) using post-update hooks that don't care whether they are

3) using post-update hooks *only* with git-cvsserver, and
relying on the hook being called just before the update.

git: use run_command() to execute dashed externals
We used to simply try calling execvp(); if it succeeded, then we were done
and the new program was running. If it didn't, then we knew that it wasn't
a valid command.
Unfortunately, this interacted badly with the new pager handling. Now that
git remains the parent process and the pager is spawned, git has to hang
around until the pager is finished. We install an atexit handler to do
this, but that handler never gets called if we successfully run execvp.
You could see this behavior by running any dashed external using a pager
(e.g., "git -p stash list"). The command finishes running, but the pager
is still going. In the case of less, it then gets an error reading from
the terminal and exits, potentially leaving the terminal in a broken state
(and not showing the output).
This patch just uses run_command() to try running the dashed external. The
parent git process then waits for the external process to complete and
then handles the pager cleanup as it would for an internal command.

When run_command() was asked to run a non-existant command, its behavior
varied depending on the platform:
- on POSIX systems, we would fork, and then after the execvp call
failed, we could call die(), which prints a message to stderr and
exits with code 128.
- on Windows, we do a PATH lookup, realize the program isn't there, and
then return ERR_RUN_COMMAND_FORK
The goal of this patch is to make it clear to callers that the specific
error was a missing command. To do this, we will return the error code
ERR_RUN_COMMAND_EXEC, which is already defined in run-command.h, checked
for in several places, but never actually gets set.
The new behavior is:
- on POSIX systems, we exit the forked process with code 127 (the same
as the shell uses to report missing commands). The parent process
recognizes this code and returns an EXEC error. The stderr message is
silenced, since the caller may be speculatively trying to run a
command. Instead, we use trace_printf so that somebody interested in
debugging can see the error that occured.
- on Windows, we check errno, which is already set correctly by
mingw_spawnvpe, and report an EXEC error instead of a FORK error
Thus it is safe to speculatively run a command:
int r = run_command_v_opt(argv, 0);
if (r == -ERR_RUN_COMMAND_EXEC)
/* oops, it wasn't found; try something else */
else
/* we failed for some other reason, error is in r */

Makefile: Make 'configure --with-expat=path' actually work
While the configure script sets the EXPATDIR environment variable to
whatever value was passed to its option --with-expat as the prefix of
the location of the expat library and headers, the Makefile ignored it.
This patch fixes this bug.

git: s/run_command/run_builtin/
There is a static function called run_command which
conflicts with the library function in run-command.c; this
isn't a problem currently, but prevents including
run-command.h in git.c.
This patch just renames the static function to something
more specific and non-conflicting.
