[FFmpeg-devel] [PATCH] doc/filters.texi: fix several typos in the vidstab* sections

[Moritz Barsnick]

Hi,

there are two minor typos and a stray bracket in the vidstab* sections
of the filters documentation. Patch is attached.

I also took the liberty to add references to the other filter (unsharp)
which is mentioned, and had to add an anchor to the unsharp section for
this. Some other sections do use @ref{} to point to other filters, some
don't. *shrug* Is there any interest in someone adding @ref{}'s
everywhere possible? I could give it a "stab". ;-)

Cheers,
Moritz

Also create an anchor for the unsharp filter, and references to
it in its mentions.
