[PATCH v4 0/5] notes.c: introduce "--separator" optio

From: Teng Long <dyroneteng@gmail.com>

Sorry for the late patch, my family just recovered from COVID-19.

Diff from v3:

     * rename option name from '--blank-line' to '--separator'

Thanks.

Teng Long (5):
  notes.c: cleanup 'strbuf_grow' call in 'append_edit'
  notes.c: cleanup for "designated init" and "char ptr init"
  notes.c: drop unreachable code in 'append_edit()'
  notes.c: provide tips when target and append note are both empty
  notes.c: introduce "--separator" option
