[PATCH v3 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 V2:

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

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
