local to subdatasets paths in action status report are misleading

[yarikoptic]

if before (0.11.x) it was suboptimal due to full paths:

(git-annex)hopa:/tmp/testds-remove[master]git-annex
$> echo 123 >> subds/subds12/subds/ingit 
(dev) 1 14595 [2].....................................:Mon 20 May 2019 06:38:30 PM EDT:.
(git-annex)hopa:/tmp/testds-remove[master]git-annex
$> datalad save -r -d . subds/subds12/subds/ingit
save(ok): /tmp/testds-remove/subds/subds12/subds (dataset)
save(ok): /tmp/testds-remove/subds/subds12 (dataset)
save(ok): /tmp/testds-remove/subds (dataset)
save(ok): /tmp/testds-remove (dataset)
action summary:
  save (ok: 4)

Now (0.12.0rc4.dev5) it is easier on eyes but without consideration of the "context" from which the command was called, reported paths within subdatasets could be confusing, wrong, or misleading:

(git-annex)hopa:/tmp/testds-remove[master]git-annex
$> echo 123 >> subds/subds12/subds/ingit
(dev) 1 14599 [2].....................................:Mon 20 May 2019 06:39:20 PM EDT:.
(git-annex)hopa:/tmp/testds-remove[master]git-annex
$> datalad save -r -d . subds/subds12/subds/ingit
add(ok): ingit (file)
save(ok): subds/subds12/subds (dataset)
add(ok): subds (file)
save(ok): subds/subds12 (dataset)
add(ok): subds12 (file)
save(ok): subds (dataset)
add(ok): subds (file)
save(ok): . (dataset)
action summary:
  add (ok: 4)
  save (ok: 4)

not to mention that I am not sure what "add(ok): subds (file)" means since I do not have subds file in this example.
