We already deleted these, but libav did not: 14360e07, a96b171,
f234cd0. They were re-introduced by a recent merge from libav and
reverting it might make more sense than this patch, but I don't know
what is preferable. I should have mentioned that.

I do not believe there is a reason to have both the text file presets
and the ability to access them directly with -preset/-vprofile. Seems
redundant and confusing for users.

You already did document the lossless presets with eb11cca and the
change from file based presets was mentioned on the web site May 3,
2011, but yes, more documentation is good.
