[WISH LIST] Remove leading spaces in notes

[Tor Kringeland]

Currently if you insert a note on a heading that has double newlines in
it, the empty newlines will be padded with spaces.  For example

#+begin_example
* heading
  - Note taken on [2022-07-26 Tue 16:00] \\
    note with
    
    newlines it in
#+end_example

It would be nice to (if this is not considered a bug) to have an option
which would not insert these unecessary spaces when adding notes
