99e09dafd7 interpret-trailers: add --parse convenience option
The last few commits have added command line options that
can turn interpret-trailers into a parsing tool. Since
they'd most often be used together, let's provide a
convenient single option for callers to invoke this mode.

This is implemented as a callback rather than a boolean so
that its effect is applied immediately, as if those options
had been specified. Later options can then override them.
E.g.:

  git interpret-trailers --parse --no-unfold

would work.

Let's also update the documentation to make clear that this
parsing mode behaves quite differently than the normal
"add trailers to the input" mode.

000023961a interpret-trailers: add an option to unfold values
The point of "--only-trailers" is to give a caller an output
that's easy for them to parse. Getting rid of the
non-trailer material helps, but we still may see more
complicated syntax like whitespace continuation. Let's add
an option to unfold any continuation, giving the output as a
single "key: value" line per trailer.

As a bonus, this could be used even without --only-trailers
to clean up unusual formatting in the incoming data.

fdbdb64f49 interpret-trailers: add an option to show only existing trailers
It can be useful to invoke interpret-trailers for the
primary purpose of parsing existing trailers. But in that
case, we don't want to apply existing ifMissing or ifExists
rules from the config. Let's add a special mode where we
avoid applying those rules. Coupled with --only-trailers,
this gives us a reasonable parsing tool.

56c493ed1b interpret-trailers: add an option to show only the trailers
In theory it's easy for any reader who wants to parse
trailers to do so. But there are a lot of subtle corner
cases around what counts as a trailer, when the trailer
block begins and ends, etc. Since interpret-trailers already
has our parsing logic, let's let callers ask it to just
output the trailers.

They still have to parse the "key: value" lines, but at
least they can ignore all of the other corner cases.

0ea5292e6b interpret-trailers: add options for actions
Allow using non-default values for trailers without having to set
them up in .gitconfig first.  For example, if you have the following
configuration

     trailer.signed-off-by.where = end

you may use "--where before" when a patch author forgets his
Signed-off-by and provides it in a separate email.  Likewise for
--if-exists and --if-missing

Reverting to the behavior specified by .gitconfig is done with
--no-where, --no-if-exists and --no-if-missing.

b275da816c Documentation: fix reference to ifExists for interpret-trailers
The manual for "git interpret-trailers" mentioned a non-existing
literal `overwrite` for its config option `trailer.ifexists`.  The
correct name for that choice is `replace`.

df616b19b4 doc: mention user-configured trailers
In commit 1462450 ("trailer: allow non-trailers in trailer block",
2016-10-21), functionality was added (and tested [1]) to allow
non-trailer lines in trailer blocks, as long as those blocks contain at
least one Git-generated or user-configured trailer, and consists of at
least 25% trailers. The documentation was updated to mention this new
functionality, but did not mention "user-configured trailer".

Further update the documentation to also mention "user-configured
trailer".

60ef86a162 trailer: support values folded to multiple lines
Currently, interpret-trailers requires that a trailer be only on 1 line.
For example:

a: first line
   second line

would be interpreted as one trailer line followed by one non-trailer line.

Make interpret-trailers support RFC 822-style folding, treating those
lines as one logical trailer.

c463a6b280 trailer: forbid leading whitespace in trailers

146245063e trailer: allow non-trailers in trailer block
Currently, interpret-trailers requires all lines of a trailer block to
be trailers (or comments) - if not it would not identify that block as a
trailer block, and thus create its own trailer block, inserting a blank
line.  For example:

  echo -e "\nSigned-off-by: x\nnot trailer" |
  git interpret-trailers --trailer "c: d"

would result in:

  Signed-off-by: x
  not trailer

  c: d

Relax the definition of a trailer block to require that the trailers (i)
are all trailers, or (ii) contain at least one Git-generated trailer and
consists of at least 25% trailers.

  Signed-off-by: x
  not trailer
  c: d

(i) is the existing functionality. (ii) allows arbitrary lines to be
included in trailer blocks, like those in [1], and still allow
interpret-trailers to be used.

bcf9626a71 doc: typeset long command-line options as literal
Similarly to the previous commit, use backquotes instead of
forward-quotes, for long options.

This was obtained with:

  perl -pi -e "s/'(--[a-z][a-z=<>-]*)'/\`\$1\`/g" *.txt

and manual tweak to remove false positive in ascii-art (o'--o'--o' to
describe rewritten history).

Add a command line option --in-place to support in-place editing akin to
sed -i.  This allows to write commands like the following:

  git interpret-trailers --trailer "X: Y" a.txt > b.txt && mv b.txt a.txt

in a more concise way:

  git interpret-trailers --trailer "X: Y" --in-place a.txt
