First of all: Thanks for working on this! This looks like a really
good start. Plenty of comments below (mostly either to learn myself,
or to check what alternatives you've considered), but overall, I'm
happy about where this is going.

>         git interpret-trailers

Pesonally, I'd rather name it "git process-footers", since I think
"process" better captures the two-way functionality of this program
(both parsing/interpreting _and_ generating/writiing), and I believe
I'm not alone in preferring "footer" over "trailer". That said, this
is certainly bikeshedding territory, and I am not the one writing the
code, so feel free to ignore.

As has been asked earlier in this discussion, we should probably
specify explicitly what we _mean_ with "RFC822-style"
headers/footers/trailers, and exactly how closely we follow the actual
RFC... E.g. do we make use of the linebreaking rules? encoding
handling? etc... We may want to take a more relaxed approach (after
all, we're not including a complete RFC822/RFC2822 implementation),
but we should at least state so, and possibly how/why we do so.

--trim-empty will remove empty footers given on the command-line? Or
in the infile? or both? I think I'm fine with both, but I wonder if
there is a use case for treating the two types of empty footers
separately...

If the output is written to stdout, then why is not the input taken
from stdin? Or vice versa: why not --outfile?

>         - the "trailer.<token>.value" options in the config are interpreted

This is the default value of the footer if not further specified on
the command-line?

Not sure what these two options will do, or what kind of values they take...

>         - the "trailer.<token>.command" config option

I guess the value of .command is executed to generate the default
content of the footer?

As stated above, I prefer "footer" over "trailer"...

Maybe at least split in two:
 - One patch to deal with the administrivia of adding a new command.
 - One (or more) patch(es) to introduce the logic/functionality of the
new command.

When discussing RFC822-style headers (or in our case,
footer/trailers), one often talks about a "field" which consists of a
"field name" and a "field value" (or "field body"). I propose that we
use the same naming convention in our code.

Here, I assume 'tok' is the field name, and 'val' is the field value.
Maybe rename to "name" and "value", respectively?

So both '=' (preferred) and ':' are accepted as field/value
separators. That's ok for the command-line, I believe.

>From the enum values, I assume that these declare the desired behavior
when there are two (or more?) or the same footer (i.e. same "field
name"). However, it's not (yet) obvious to me in which order they are
processed. There are several opportunities for multiple instances of
the same "field name":

 - Two (or more) occurences in the infile
 - Two (or more) occurences on the command line
 - One occurence in the infile, and one of the command line

It is not obvious to me in which order these are processed, or which
of those cases constitute a duplicate/repetition, hence it's not clear
to me what the result will be when e.g. using OVERWRITE. Also not sure
what DONT_REPEAT means, and if/how it's different from OVERWRITE.
Instead, I suggest we should specify clearly:

 1. In which order are the footers processed
 2. What constitutes a repetition/duplicate (IMHO all of the above three cases)
 3. Better enum names that are easily understood given the rules in #1
and #2, I suggest:

enum handle_duplicates { KEEP_FIRST, KEEP_LAST, KEEP_ALL };

> +enum style_if_missing { DONT_APPEND, APPEND };

enum handle_missing { SKIP, INCLUDE }; ?

Is this the field _name_ or field _value_?

> +       char *command;

I assume this is only used when trailer.<token>.command is used?

Consider splitting the parsing of values -> enums into helper
functions, to make this function shorter and its logic more easily
followed.

I guess this if-block might be filled by a later commit, but is there
any reason to have the empty block in this commit?

So tok_alnum_len is the length of the initial run of alphanumeric
characters in tok (i.e. does not include '-'?)

We're iterating through the footers we found in infile?

What is held in item->string? and what is held in info->value, and why
are _both_ being compared to (the initial run of alphanumerics in)
tok?

This means that if the footers end up in multiple paragraphs, like this:

    Tested-by: foo
    Reviewed-by: bar

    Signed-off-by: xyzzy
    Signed-off-by: zyxxy

then only the latter of these two sections will be considered? What
about instead looking for the last line (i.e. first line from bottom)
that neither (a) contains ':' or (b) consists solely of zero or more
whitespace (blank lines)? Maybe also want to tighten rule (a) to only
match lines that consist of a single word (i.e. no inter-word spaces)
before the ':' (i.e. something like "^\s*[a-zA-Z0-9-]+\s*:" in
regexp-speak).

That's all I had time for now. Hopefully, I'll have some more time to
continue the review later.


Hope this helps,
