To head off any suggestions, removing cachemode:unsafe doesn't fix it.

These patches clarify and fix the documentation for the recent qemu-img
src_mode (-T) option.

qemu-img: clarify src_cache option documentation

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
The src_cache option (-T) specifies the cache mode for backing files.
It applies both the image's old backing file as well as the new backing
file:
ret = bdrv_open(&bs_old_backing, backing_name, NULL, NULL, src_flags,
old_backing_drv, &local_err);
if (ret) {
...
}

Hi Marc,
I gave it a try for various host/target combinations involving ppc64 and
x86_64. Here is what I get:
