Subject: [PATCH 11/19] qemu-img: clarify src_cache option documentation

O-Subject: [RHEL-7.1 qemu-kvm PATCH v2 3/4] qemu-img: clarify src_cache option documentation
Bugzilla: 1138691

From: Stefan Hajnoczi <stefanha@redhat.com>

The source cache option takes the same values as the cache option.  The
documentation reads a little strange because it starts with "In contrast
the src_cache option ...".  The fact that this is comparing with the
previous documented option (the 'cache' option) is implicit.  Readers
may be confused, especially if they jump to src_cache without reading
cache documentation first.
