mailinfo: make ">From" in-body header check more robust

Since commit 81c5cf7 (mailinfo: skip bogus UNIX From line inside
body, 2006-05-21), we have treated lines like ">From" in the body as
headers. This makes "git am" work for people who erroneously paste
the whole output from format-patch:

  From 12345abcd...fedcba543210 Mon Sep 17 00:00:00 2001
  From: them
  Subject: [PATCH] whatever

into their email body (assuming that an mbox writer then quotes
"From" as ">From", as otherwise we would actually mailsplit on the
in-body line).

However, this has false positives if somebody actually has a commit
body that starts with "From "; in this case we erroneously remove
the line entirely from the commit message. We can make this check
more robust by making sure the line actually looks like a real mbox
"From" line.

Inspect the line that begins with ">From " a more carefully to only
skip lines that match the expected pattern (note that the datestamp
part of the format-patch output is designed to be kept constant to
help those who write magic(5) entries).

except that it does not include the ' (' prefix or ')' suffix provided
by '%d'.

refs: make rev-parse --quiet actually quiet

When a reflog is deleted, e.g. when "git stash" clears its stashes,
"git rev-parse --verify --quiet" dies:

	fatal: Log for refs/stash is empty.

The reason is that the get_sha1() code path does not allow us
to suppress this message.

Pass the flags bitfield through get_sha1_with_context() so that
read_ref_at() can suppress the message.

Use get_sha1_with_context1() instead of get_sha1() in rev-parse
so that the --quiet flag is honored.

mailinfo: work around -Wstring-plus-int warning

The just-released Apple Xcode 6.0.1 has -Wstring-plus-int enabled by
default which complains about pointer arithmetic applied to a string
literal:

        adding 'long' to a string does not append to the string
            return !memcmp(SAMPLE + (cp - line), cp, strlen(SAMPLE) ...

Merge branch 'hj/pretty-naked-decoration'

The pretty-format specifier "%d", which expanded to " (tagname)"
for a tagged commit, gained a cousin "%D" that just gives the
"tagname" without frills.
