        Requesting we remove a module here only hides the generated documentation on pkg.go.dev.
        It does not affect the behaviour of proxy.golang.org or the go command.
        Instead we recommend using the retract directive which will be processed by all 3 of the above.

// record is formatted as:
//
//	"%d %s=%s\n" % (size, key, value)

// forces us to be a more liberal.
// Thus, we only reject all keys with NUL, and only reject NULs in values
// for the PAX version of the USTAR string fields.
