[PATCH-v2] Make git status print a helpful death message if the disk is full

[PATCH-v2] Make git status print a helpful death message if the disk is full

[David Reiss]

The old behavior just said that it failed.  Now it includes the error
information, which makes it much easier to debug.

There is a risk that some failure paths could result in misleading error
messages that actually make debugging more difficult.
