[PATCH v4 0/3] send-email: shell completion improvements

"git send-email" completion (bash, zsh) is inconsistent, its flags are split into both git-completion.bash and git-send-email.perl, and it only emits format-patch flags.

Make shell completion uniform, centralizing completion options on git-send-email.perl.

Make "git send-email --git-completion-helper" properly emit send-email specific options.

Additionally, update git-send-email(1) man page to explicitly mention format-patch options.

Differences from V3:

- Incorporate Carlo Arenas' code suggestions, adding all flags
  exhaustively.
- Incorporate Bagas Sanjaya's suggestion.

Differences from V2:

- Incorporate Junio's code suggestions.
- Follow proper conventions for git commit messages.

Carlo suggests to generate the flags programatically from the perl script. I am looking into this and already have a proof-of-concept working and plan to submit it as a separate patch series. I would like to get this series checked in first though.

Thiago Perrotta (3):
  send-email: terminate --git-completion-helper with LF
  send-email: move bash completions to core script
  send-email docs: add format-patch options
