Not here, looking at the kernel source, it splits out the interpreter
field (/bin/sh) and passes the rest of the line as single opaque
argument to the interpreter, so if I write
#!/bin/sh -- blah
the kernel does the equivalent of
{
char *argv[3];
argv[0] = "/bin/sh";
argv[1] = "-- blah";
argv[2] = 0;
execve(argv[0], argv, environ);
/* error handling here */
}
