hghave: avoid a deadlock reading the child process's output

The output of `pylint` is voluminous enough that it fills the buffer on Windows,
and waited for the parent to read it out.  But the parent was waiting on the
child to exit.

I'm not sure what the intent of setting `ret = -1` in the exception handler just
above this was...

{
    // Enforcing
    "eqeqeq"        : true,     // true: Require triple equals (===) for comparison
    "forin"         : true,     // true: Require filtering for..in loops with obj.hasOwnProperty()
    "freeze"        : true,     // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
    "nonbsp"        : true,     // true: Prohibit "non-breaking whitespace" characters.
    "undef"         : true,     // true: Require all non-global variables to be declared (prevents global leaks)

    // Environments
    "browser"       : true      // Web Browser (window, document, etc)
}
