        * doc/invoke.texi (-fuse-linker-plugin): Improve grammar.

I was going to commit a smaller version of this patch as obvious (just
the second of the three hunks in the patch) but I spotted a few other
improvements that could be made. I think my changes preserve the
intended meaning, but improve the English slightly and (I hope)
clarify it.

OK for trunk?

Would removing "do" from "and shared libraries that do use hidden
visibility" be a further improvement?
