trailer: clarify failure modes in parse_trailer
The parse_trailer function has a few modes of operation, all depending on whether the separator is present in its input, and if yes, the separator's position. Some of these modes are failure modes, and these failure modes are handled differently depending on whether the trailer line was sourced from a file or from a command-line argument. Extract a function to find the separator, allowing the invokers of parse_trailer to determine how to handle the failure modes instead of making parse_trailer do it. In this function, also take in the list of separators, so that we can distinguish between command line arguments (which allow '=' as separator) and file input (which does not allow '=' as separator).
