Good catch.

However, it may make more sense to switch to using the "args" field
instead of the "argv" field: it is of type "struct argv_array" and is
released automagically by finish_command().

In other words, you would use something like

@@ -600,7 +601,8 @@ static struct cmd2process
*start_multi_file_filter(struct hashmap *hashmap, cons
        process = &entry->process;

        child_process_init(process);
-       process->argv = argv;
+	argv_array_push(&process->args, cmd);

instead, making even for a nice LOC reduction.

Ciao,
Johannes
