User who want to avoid refering to none-existing variables got earlier the
following error.
$ set -u
$ findmnt --output <tab>bash: OUTPUT: unbound variable
Here is short explanation of this setting.
$ help set
-u Treat unset variables as an error when substituting.

This solution can become messy when you have too many options listed,
because it repeats all of them. For example, after invoking completion
with this input:
$ partx --output END,SECTORS,SCHEME,START,
You got these completions:
END,SECTORS,SCHEME,START,FLAGS, END,SECTORS,SCHEME,START,NR,
END,SECTORS,SCHEME,START,TYPE,
END,SECTORS,SCHEME,START,NAME, END,SECTORS,SCHEME,START,SIZE,
END,SECTORS,SCHEME,START,UUID,
Nevertheless, it works even with numbers (listed options properly
excluded from completion). Try to invoke completion after
'chcpu --disable ' or 'lsblk --exclude ' to see it in action.
Few issues remained:
* completion interrupts after encountering ':' in listed option,
like in 'MAJ:MIN' in lsblk, losetup.
* lscpu completion is broken: it inserts space after '--extended',
but lscpu assumes there is no space after this option. It also
doesn't complete '--parse' option.
* some completion options are outdated (for example, lscpu MMHZ). We
need to sync them with code. Fix for lscpu follows.

The initial bash-completion missed swapon options -L and -U. Use of
block device was proposed to be more appropriate than a path to a file.

Users who know the short options can just hit the short option instead
of tab, and it's not likely that it would be helpful to present a list
of single character options to users who don't know them, doing so
just unnecessarily trashes the list of suggestions.
