I find a recentf-keep variable in vers. 22 and 23 but no 
recentf-include. Anyway I evaluated the expression but it didn't prevent 
any types of files from being added to the list. Your first regular 
expression in the list with bar disjunction doesn't have a backtick to 
match the tick before the double quote; is this on purpose? I don't see 
how the first regexp specifies any number of characters before tex or 
txt and the second no characters. It looks like tex and txt are kept if 
I change the variable in your expression to recentf-include but .emacs 
isn't added to the list.
