If it helps msys, I think we should allow compiling things in, but this
"compiled in default for the platform, and possible per-repository
override" made me a bit confused:

 (1) in your "This is Linux and on sane filesystems I do not weaken it to
     rename but on this one filesystem I do" case can be handled by adding
     .git/config in that repository;

 (2) problems with msysgit can be handled by compiled-in defaults as long
     as the user does not have .git/config entry to say "link";

 (3) if you use the same repository from both sides with (1), presumably
     by dual-booting, so having .git/config that says "rename" happens to
     work;

 (4) if somebody has a dual-boot setup and shares a repository hosted
     natively on the Linux side by mounting it on the Windows side (Ext2
     IFS?), I wonder what should happen.  While you are using the
     repository from the Linux side, you may not want to weaken it to use
     "rename" (so you do not add .git/config that says "rename").  When
     you are accessing it over Ext2 IFS, perhaps you would want to use
     "rename" (I do not know about the details of #222 and #229, so it may
     not applicable, though).

So,... as long as you do not have a triple-boot setup, third system among
which wants to use "link" on a repository where both Linux and Windows
side want to use "rename", I think you are Ok.
