[Bug-tar] quoting-style=escape misdescribed in tar.texi

[Chapman Flack]

Hi,

I found a slight mistake in tar.texi, and I can see it is still
present on the git head:

Around line 8479, and again around 8611, the 'escape' style
is described as adding a backslash before a space. That is not
what tar actually does, it leaves spaces unchanged (I've tried
1.26 here, but that is also what you see in the example
immediately following, around line 8619 in the doc.) In other words,
the *example* correctly matches what the program does, only
the *description* is wrong.

The rest of the rules seem to be presented correctly, it is
only wrong about the space.

There's a related goof around lines 8514 and 8519, where it
suggests a plain 'ls' command would list the names as shown,
but it does not; only 'ls -b' produces that form of output.
(And ls -b *does* add a \ before a space, as tar in 'escape'
style does not. The example there is correct too.)

Cheers,
Chapman Flack
