But when I am reproducing your solution, I may be in trouble:
If we let shell-script `exit(1)`, `capture_command()` will output
"running trailer command '%s' failed" which is its origin strategy
in order to catch the user's command error.

Yes, if we were to take that route, the trailer.c code needs to be
taught to conditionally not to pass $1, and capture_command() needs
to be taught to conditionally be silent on non-zero exit, as it now
is a perfectly sane for the program to exit with non-zero status in
some cases (like this one).
