cli_classic: Tidy up some repeated handling patterns into funcs

Browse Source 
Introduce cli_classic_single_operation() to consolidate the repeating
pattern of multiple CLI operations at once. Also modify
cli_classic_abort_usage() to take an optional error abort string and
print it to stderr, this allows for trimming a few more lines off the
cli implementation.

V.2: A few fixes upon review:
  - Trim off some unnecessary braces for single line branches.
  - Pass 'operation_specified' by reference.
  - Rename a function.
V.3: Fix print order of cli_classic_abort_usage().
