Those settings enforce convergence on common coding style with respect to whitespace.
Do not use tabs to indent with shell scripts because those tabs most often
serve the function of triggering command completion. Which could end a
command before it is pasted completely.
Traditionally indentation is two spaces here, not four.
Other rules will catch stray whitespace at the end of lines or files, which,
once committed, would annoy the next developer because his editor would strip
them from lines he did not intended to modify in the first place.
When thy variables henceforth accept blessed white-space,
guided will thy scripture be along righteous path(s).

Caddy's dist files sometimes ended up being owned by matt:staff or other
quite arcane and/or frightening names. If someone extracting didn't pay
attention a regular user who happened to have same uid by accident could
later tamper with the files' contents. It's 0:0 from now on.
Use all available threads when packaging distributables
Caddy binaries will be added to their archives in-place: This change
eliminates them being renamed within dist/builds one after another.
As does 'gox', dist/automate.sh will spare one available thread if possible.
Format of main.buildDate has been locale-dependent,
and is now ISO-8601 compliant.
Caddy displayed with ```-version``` something like (mind the datetime format):
Caddy 0.8.2 (+591b209 Fri Mar 18 21:22:55 UTC 2016)
2 files changed, 9 insertions(+), 4 deletions(-)
build.bash
main.go
which is now:
Caddy 0.8.2 (+591b209 2016-03-18 21:22:55Z)
2 files changed, 9 insertions(+), 4 deletions(-)
build.bash,main.go

Unlike network.target the network-online.target guarantees that the network
devices are online.
If you bind to 0.0.0.0, [::], [::1], and/or 127.0.0.1 only that is enough to
proceed. But in case a particular IP is needed, like ${COREOS_PUBLIC_IPV4},
we require any IP assignments to have completed before Caddy's start. That
is achieved by depending on systemd-networkd-wait-online.service (which is
scheduled before network-online.target, then, automatically).
