Eli,
as discussed in 

	http://article.gmane.org/gmane.comp.gdb.patches/33695

you want some changes to frozen varobj docs I've previously
committing. Sorry it took me so long, but the attached patch
fixes all concerns you've raised. OK?

Incidentally, I still find it strange that '-var-update' anchor
actually points to the middle of '-var-update' documentation.
Do you think this is something we should fix as a separate patch?
