[PATCH v6 0/3] send-email: shell completion improvements

Differences from V5:

Addresses original Ævar's patch:

- Effectively including all combined options, which ends up adding
  --dump-aliases and --identity.

- Manually excluded --h and --git-completion-helper. This is consistent
  with "git format-patch --git-completion-helper".

- Completely dropped sorting, because it seems the current git
  subcommands don't really care about it (I verified "git format-patch"
  and "git apply" only).

As mentioned earlier, the following issue remains open:

"The following options exist in GetOptions but not in the current
usage string:

--no-signed-off-cc --sender --signed-off-cc"

I wouldn't mind adding a fourth patch to this series that fixes the
current usage, just let me know which wording you'd like me to add.

Finally, I will note that I haven't touched the third patch of this
series (git-send-email.txt) because it is not obvious to me which
direction we're taking. My understanding is that Junio prefers to leave
things as is, but let me know if I should change it to e.g. Carlos' or
Bagas' version.

  send-email: terminate --git-completion-helper with LF
  send-email: programmatically generate bash completions
  send-email docs: add format-patch options
