Also, many options that have their own --verbose option should update
the help text to note that it's an alias of the global.
I'm going to take another look today, the scope of the change might be
too big to do in one go so some incremental steps might be needed.
As global verbose depends on the local verbose to log messages, if
local verbose used stderr then the global verbose uses the stderr.
For example
patch:
btrfs-progs: send: use global verbose and quiet options
------------------
./btrfs send --help
<snip>
-v|--verbose enable verbose output to stderr, each occurrence of
this option increases verbosity
-q|--quiet suppress all messages, except errors
Global options:
-v|--verbose increase output verbosity
-q|--quiet print only errors
------------------
IMO verbose should be stdout. Should it be ok to change to stdout as it
is under verbose?
Thanks.
