The command
printf "body\n\ntest: foo\ntest: froz\n" | git -c
trailer.test.key=tested -c trailer.test.command="echo by \$ARG"
interpret-trailers
gives:
body
tested: foo
tested: froz
tested: by froz
I expected the command to be run on each "test" key, resulting in the
output:
body:
tested: by foo
tested: by froz
(In a real life scenario, I would use ifexists replace.)[*]
Maybe my expectation is wrong? The code breaks out of the loop after the
first matching in_tok, apparently intentionally so. But I'm not sure -
the key is replaced for both instances.
Simply replacing that "return 1" by a "ret = 1" etc. runs into problems
with the way the freeing of in_tok and arg_tok is arranged there :|
Basically, I expected the trailer command to work "grep/sed-like" on all
key value pairs that have matching keys, passing the value to the
command, and using the (each) command's output as the new value for each
of these pairs.

[*] My prime use case: fill in reported-by etc. with short author names,
completed the same way we complete --author=jun using a trailer command
(interpret-trailers in the commit-msg hook):
$ git help author
`git author' is aliased to `!f() { a=$(git log -1 --all -i --format="%aN
<%aE>" --author "$1"); echo ${a:-$1}; }; f'
$ cat .git/hooks/commit-msg
#!/bin/sh
git interpret-trailers --in-place "$1"
$ git config --get-regexp trailer
trailer.report.key Reported-by
trailer.report.command git author '$ARG'
trailer.report.ifexists replace
trailer.report.ifmissing doNothing
