May be a git problem:
in sha1_file.c move_temp_to_file tries to rename or unlink and link
to move the temp file. But the file has a strange set of permisions.
In sha1_file.c in create_tmpfile()
fd = git_mkstemp_mode(buffer, 0444);
This then results in wrapper.c git_mkstemps_mode()
fd = open(pattern, O_CREAT | O_EXCL | O_RDWR, mode);
0444 looks strange for a file that is meant to be read and written
or renamed. But 0444 this mode is used in other places in git as well.
I would expect 0666 to be used.
Some combination of Windows and Samba or AFS processing causes
a permission problem, where as Unix may let the owner still
write or at least rename or link the file.
