74a74beee9 Merge branch 'lt/mailinfo-in-body-header-continuation'
If a patch e-mail had its first paragraph after an in-body header
indented (even after a blank line after the in-body header line),
the indented line was mistook as a continuation of the in-body
header.  This has been fixed.

fd1062e52e mailinfo: fix in-body header continuations
An empty line should stop any pending in-body headers, and start the
actual body parsing.

This also modifies the original test for the in-body headers to actually
have a real commit body that starts with spaces, and changes the test to
check that the long line matches _exactly_, and doesn't get extra data
from the body.

08414938a2 mailinfo.c: move side-effects outside of assert
Since 6b4b013f18 (mailinfo: handle in-body header continuations,
2016-09-20, v2.11.0) mailinfo.c has contained new code with an
assert of the form:

	assert(call_a_function(...))

The function in question, check_header, has side effects.  This
means that when NDEBUG is defined during a release build the
function call is omitted entirely, the side effects do not
take place and tests (fortunately) start failing.

Since the only time that mi->inbody_header_accum is appended to is
in check_inbody_header, and appending onto a blank
mi->inbody_header_accum always happens when is_inbody_header is
true, this guarantees a prefix that causes check_header to always
return true.

Therefore replace the assert with an if !check_header + DIE
combination to reflect this.

rfc2822 has provisions for quoted strings in structured header fields,
but also allows for escaping these with so-called quoted-pairs.

The only thing git currently does is removing exterior quotes, but
quotes within are left alone.

Remove exterior quotes and remove escape characters so that they don't

6b4b013f18 mailinfo: handle in-body header continuations
Mailinfo currently handles multi-line headers, but it does not handle
multi-line in-body headers. Teach it to handle such headers, for
example, for this input:

  From: author <author@example.com>
  Date: Fri, 9 Jun 2006 00:44:16 -0700
  Subject: a very long
   broken line

  Subject: another very long
   broken line

interpret the in-body subject to be "another very long broken line"
instead of "another very long".

An existing test (t/t5100/msg0015) has an indented line immediately
after an in-body header - it has been modified to reflect the new
functionality.

8f309aeb82 strbuf: introduce strbuf_getline_{lf,nul}()
The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago.  No useful caller that uses other value has emerged.

By now, it is clear that the interface is overly broad without a
good reason.  Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.

This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them.  The changes contained in this patch are:

 * introduction of these two functions in strbuf.[ch]

 * mechanical conversion of all callers to strbuf_getline() with
   either '\n' or '\0' as the third parameter to instead call the
   respective thin wrapper.

After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller.  An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

85d9d9ddf3 mailinfo: fix passing wrong address to git_mailinfo_config
git_mailinfo_config() expects "struct mailinfo *". But in
setup_mailinfo(), "mi" is already "struct mailinfo *". &mi would make
it "struct mailinfo **" and git_mailinfo_config() would damage some
other memory when it assigns some value to mi->use_scissors.

This is caught by t4150.20. git_mailinfo_config() breaks
mi->name.alloc and makes strbuf_release() in clear_mailinfo() attempt
to free strbuf_slopbuf.

669b963af2 mailinfo: handle charset conversion errors in the caller
Instead of dying in convert_to_utf8(), just report an error and let
the callers handle it.  Between the two callers:

 - decode_header() silently punts when it cannot parse a broken
   RFC2047 encoded text (e.g. when it sees anything other than B or
   Q after it sees "=?<charset>") by jumping to release_return,
   returning the string it successfully parsed out so far, to the
   caller.  A piece of string that convert_to_utf8() cannot handle
   can be treated the same way.

 - handle_commit_msg() doesn't cope with a malformed line well, so
   die there for now.  We'll lift this even higher in later changes
   in this series.

ef29c11702 mailinfo: More carefully parse header lines in read_one_header_line()
We exited prematurely from header parsing loop when the header
field did not have a space after the colon but we insisted on
it, and we got the check wrong because we forgot that we strip
the trailing whitespace before we do the check.

The space after the colon is not even required by RFC2822, so
stop requiring it.  While we are at it, the header line is
specified to be more strict than "anything with a colon in it"
(there must be one or more characters before the colon, and they
must not be controls, SP or non US-ASCII), so implement that
check as well, lest we mistakenly think something like:

	Bogus not a header line: this is not.

as a header line.

8b4525fb3c Refactor commit messge handling.
- Move handle_info into main so it is called once
  after everything has been parsed.  This allows the removal
  of a static variable and removes two duplicate calls.

- Move parsing of inbody headers into handle_commit.
  This means we parse the in-body headers after we have decoded
  the character set, and it removes code duplication between
  handle_multipart_one_part and handle_body.

- Change the flag indicating that we have seen an in body
  prefix header into another bit in seen.
  This is a little more general and allows the possibility of parsing
  in body headers after the body message has begun.
