git not allowing 744 as permissions for a file

[Auriane Reverdell <areverdell@xxxxxxxxx>]

Hi,

git doesn't allow to add the execution permission on a file only for
the user. A chmod 744 on a file will transform into 755 when added to
git. This can potentially lead to security problems on certain
systems. Is there a way to fix that? I'll be happy to do so if
somebody shows me where to do it.
