[PATCH v2] repack.c: Use move_temp_to_file() instead of rename()

["Torsten Bögershausen" <tboegi@web.de>]

In a1bbc6c0 a shell command "mv -f" was replaced with the rename() function.

Use move_temp_to_file() from sha1_file.c instead of rename().
This is in line with the handling of other Git internal tmp files,
and calls adjust_shared_perm()

Thanks for all comments.
I haven't been able to reproduce the problem here.
Tips and information how to reproduce it are wellcome.

I think this patch makes sense to support core.sharedRepository(),
but I haven't made a test case for the pack/idx files.

Jochen, doess this patch fix your problem, or do we need
another patch on top of this?
