[PATCH v7 0/3] send-email: shell completion improvements

Differences from V6:

2/3: Addresses all of Carlos's comments:
  - make indentation consistent (tabs): note that there's a giant diff
    for the largest GetOptions now, it adds a bit of noise to the patch
  - do not reuse the options variable, for improved readability.

2/3: One extra improvement:
  - deduplicate send-email and format-patch common options (for example,
    now --from appears only once)

3/3:
  - updated git-send-email.perl USAGE to be consistent with
    git-send-email(1)
  - still haven't touched anything else, waiting on Carlos's RFC patch
    ongoing discussion to settle.

Thiago Perrotta (3):
  send-email: terminate --git-completion-helper with LF
  send-email: programmatically generate bash completions
  send-email docs: add format-patch options
