[PATCH,Hurd] Fix hang on fork

Oh, was that in the message?  I must have missed it because I didn't see a
ChangeLog header.

Don't use () as if it were part of a function name.  Otherwise that is just
right (though it's ok to omit " (__fork)" in a libc file whose file name
matches the function).

I didn't bother to say that this sentence is rather awkward to a native
English speaker: s/to be having it locked/to have it locked/.

The formatting is now correct, so you can go ahead and commit.


Thanks,
