Description
Desired Behavior
When using --trace-file, for very long command lines, show arguments passed to ocaml*.exe instead of -args0 responsefile.data.
When profiling Dune and in particular external commands called with -args0 / -args it's hard/impossible to tell what was actually passed to the external command. For example, for ocamlc executions you cannot always see what source file was actually compiled.
Example
I propose that instead of logging Args: -args0 responsefile.data instead it logs Args: <content of responsefile>, so
Args: <very long list of options> -c file.ml
Alternatively, another value is logged, ReponseFileContent or similiar, with the content of the file:
Args: -args0 responsefile.data
ResponseFileContent: <very long list of options> -c file.ml
