Docs: Duplicated explanation of "quote removal" on manual

[Sebastian Carlos]

Hello,

The manual seems to repeat the same information two paragraphs apart:

On Section 3.5 Shell Expansions, a paragraph reads:

> After these expansions are performed, quote characters present in the
original word are removed unless they have been quoted themselves (quote
removal).

Then, after only one paragraph, another paragraph reads:

> After all expansions, quote removal (see Quote Removal) is performed.

I suggest removing the second one and moving the cross-reference to the
first one.

Thanks for your time.
