Actually, I was talking about 'hg help templates'.

Things that are as yet undocumented:

if(expr, then[, else])
ifeq(expr, expr, then[, else])
sub(pat, repl, expr)
join(list, sep)
label(label, expr)
date(date[, fmt])
fill(text[, width])

expr % "{template}"
expr|filter -> filter(expr)


The most frequently asked question is how to format lists like files.
Previously, this required writing a style file, but can now be done with
something like:

$ hg log --template "{files % '{rev}: {file}\n'}"
