What does the abbreviation "p.p." mean when referring to convergence? E.g. in [the following paper](https://www.jstor.org/stable/2037625) by Harry Pollard

> 
> THEOREM. If $f \in L^p$ for some $p$ in the range $\tfrac{4}{3} <p < \infty$, then its Legendre
>  series converges **p.p**. The result fails if $1 <p<\tfrac{4}{3}$.

I am familiar with convergence a.s., a.e., in probability, in expectation, etc. Does this mean point-wise?
