I do not know the origin of that code in trailers.c but it feels
quite confused and error prone to use textual replacement with
strbuf_replace().  Why doesn't the code, which knows it will use
shell to execute the command line given by the end user in the
configuration, to just export ARG as an environment variable and
be done with it?  It would also avoid quoting problem etc.
