Hi,
> Hi Roland, is `lvs --reportformat json` or `lvs
--nameprefixes` good enough?
good when using scripting / automated processing - but not good,
when we need it human readable.
i'd even would call it a bug, when using same strings for
"translated" names.
would anybody accept something like this (just for saving column
space) ? ok, that's a little bit over the top - but i wand to
underline what i mean
getpersondetails -o forename, surname, streetname, cityname
name name name name

sorry for this noise, i was too dumb for that , "-o+opt1,opt2
-o-opt3,opt4" works as desired (as documented in manpage)

also sorry for this, as we can use --separator="," (apparently did
have too much coffee and had overseen that in the manpage)
the question regarding native column headers/description remains
