Subject: Fixes for option parsing
X-Git-Tag: v1.4.0-rc1~239^2~7
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=78fff6ebbafe2d23464a2b059104954bfe8732c7;hp=cb8f64b4e3f263c113b7a2f156af74b810e969ff;p=git.git

Fixes for option parsing

Make sure "git show" always show the header, regardless of whether there
is a diff or not.

Also, make sure "always_show_header" actually works, since generate_header
only tested it in one out of three return paths.
