That looks a little bit odd. Better is this:
fu! FoldTeXLines(lnum)
if !exists("s:fold")
let s:fold = '0'
endif
let line = getline(a:lnum)
if line =~ '^\s*\\htitle'
let s:fold = '>1'
elseif line =~ '^\s*\\subtitle' && s:fold != '>1'
let s:fold = '>1'
elseif line =~ '^\s*\\clearpage'
let s:fold = '<1'
else
let s:fold = '='
endif
return s:fold
endfu

Christian
