>Description:
I know "this is the way it has been for years", but...

The output from 'mount -v' gives (what I think is) too much info (read/write/sync stats) in addition to showing what gets mounted.  I would expect the extended info to be provided with additional instances of '-v'.

I have submitted a patch below, done my best not to deviate from the NetBSD style.  This may seem egregious, but if it is not an acceptable patch I should like to know why.

I have a similar one for 'umount' on the way.
>How-To-Repeat:
WHAT I DO:
# mount -v /build

WHAT I EXPECT:
/dev/ld0k on /build type ffs
#

WHAT I GET:
/dev/ld0k on /build type ffs (local, fsid: 0x130a/0x78b, reads: sync 1 async 0, writes: sync 2 async 0)
