[PATCH v2 0/3] Clarify the documentation of options with optional arguments

Changes since v2:

* Typo in commit message

* key-id -> keyid in more places. Not so important, but we had cases
  where SYNOPSYS was saying key-id and the full doc keyid, let's make
  it more uniform (and more grep-able).

* Document what --sign-commit and --open-in-pager do when the optional
  argument is not specified.

Matthieu Moy (3):
  Documentation: use 'keyid' consistently, not 'key-id'
  Documentation/grep: fix documentation of -O
  Documentation: explain optional arguments better
