'git format-patch -o <outdir>' did an equivalent of 'mkdir <outdir>'
not 'mkdir -p <outdir>', which is being corrected.
Avoid the usage of 'adjust_shared_perm' on the leading directories which
may have security implications. Achieved by temporarily disabling of
'config.sharedRepository' like 'git init' does.
