Add two FAQs about running FFmpeg in the background.
The first explains the use of the -nostdin option in
a straightforward way. Text revised based on review.
The second FAQ starts from a confusing error message,
and leads to the solution, use of the -nostdin option.
The purpose of the second FAQ is to attract web searches
from people having the problem, and offer them a solution.
Add an anchor to the Main Options section of the ffmpeg
documentation, so that the FAQs can link directly there.

This way locally installed documentation refers to itself instead of the

The error was fixed in commit ce9bd30379
more than one year ago, and does not affect all the currently supported
versions.
In particular, fix trac issue #1535.
We used to use 'filtergraph' or 'filter graph' randomly.
'filtergraph' was chosen due to having 57 occurrences in
the documentation, whereas 'filter graph' had only 19.

It has not worked for anything other than fringe codecs (asv1/2, mdec,
mjpeg[b]) since about 2003 and nobody ever noticed or complained. This
sufficiently proves that there are no users of this option who have a
clue of what they are doing, so it is completely useless.
-same_quant is not designed to convert between quantizer scales, AFAIK.
Add example using concat protocol.

Sometimes it makes sense to replace a raw URL with some informative text
that links to the URL instead of using the raw URL itself in the text.
Also transform some mailing list references into links.
