Should the `stat` command in newtmgr be behaving similarly to the
console command where it returns a list of all stat entries available?
That was the behaviour I was expecting, though I also tried `stat list`,
`stat show` and `stat all` or just `stat` before looking at the
documentation (which didn't elaborate, but not biggie there are more
important problems to solve!).
It seems there might be an error here:
$ newtmgr -c serial1 stat
panic: runtime error: index out of range
goroutine 1 [running]:

When I run with a valid name things are fine:
$ newtmgr -c serial1 stat ble_svc_dis
Return Code = 0
Stats Name: ble_svc_dis
manufacturer_reads_stat: 0
model_reads_stat: 0
serial_reads_stat: 0
firmware_rev_reads_stat: 0
hardware_rev_reads_stat: 0
software_rev_reads_stat: 0
It seems there isn't currently a way to know via newtmgr how many stat
entries are present, although this information is available in the
console version.
I'm running the latest newtmgr available in the master branch of the repo.

PS: The stats module is great, BTW. The reason I enjoy using Mynewt so
much is the (sadly uncommon) focus on real product deployments. Details
like this make life so much easier when devices are out in the wild, but
those 'details' tend to be forgotten in a lot of tools and platforms or
a sad afterthought. So many RTOSes and platforms are overly academic and
it's refreshing that the design decisions with Mynewt are being informed
by the realities of real world product releases, and having to debug
things in the field.
