[PATCH v5 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, generating them programmatically.

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


Differences from V4:

Incorporate Carlo Arenas' and Ævar Arnfjörð Bjarmason's suggestion to
programatically generate the flags.

I tried to be concise whilst preserving readability, hopefully it's
straightforward to parse the current implementation.

Note: using --in-reply-to to the previous version in "git format-patch"
helps keep track of the context.

Thanks for the heads up, I am slowly getting used to this email
workflow, this is my first contribution. Hopefully I got it right this
time.

Isn't this just:

my @params = <getopts list>;
GetOptions(@params);

Let me know if the regex approach I went with is OK. You seem to have
suggested me to do something with the `GetOptions` module, but I'm
afraid I only know the basics of Perl.

I tried to do something like `GetOptions($USAGE)` but it didn't quite
work (clearly I have no idea how to do that :P). If you have something
specific in mind, I'd appreciate if you could send a small patch back
that I can incorporate. Otherwise, either way, the current regex
approach isn't too horrible and seems to be reasonably reliable.
