[PATCH v3] send-pack: avoid redundant "pack-objects died with strange error"

[Jonathan Nieder <jrnieder@gmail.com>]

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant.  The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).

Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.

So leave off the "strange error" messages.

The result should look something like this:

	$ git push sf master
	Counting objects: 21542, done.
	Compressing objects: 100% (4179/4179), done.
	fatal: Unable to create temporary file: Permission denied
	error: pack-objects died of signal 13
	error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
	$

Or in the "controlled exit" case (contrived example):

	[...]
	fatal: delta size changed
	error: failed to push some refs to 'ssh://example.com/foo/bar'
	$

That was invented example output.

Googling for "pack-objects died with strange error" gives me [1], with
v1.6.2:

	$ git push
	Counting objects: 68, done.
	Delta compression using 2 threads.
	Compressing objects: 100% (50/50), done.
	Connection to SERVER closed by remote host.
	error: pack-objects died with strange error
	error: failed to push some refs to 'SERVER:PROJECT.git'

and [2], with v1.6.4.4:

	Counting objects: 4364, done.
	Delta compression using up to 2 threads.
	Compressing objects: 100% (4240/4240), done.
	error: pack-objects died with strange error | 44 KiB/s   
	error: failed to push some refs to 'mysite:main_site_repo'

and some similar examples.  All involve git versions before
v1.6.5-rc0~86^2~5 (run_command: report system call errors instead of
returning error codes, 2009-07-04) and after a triage turn out to be
signals.

Let's go with your fix (thanks!).
