knitr 1.48

BUG FIXES

• Fix regression from 1.46 with collapse = TRUE option not correctly collapsing source code and output into one when code chunk returns multiple outputs (thanks, @jennybc, @florisvdh, tidyverse/reprex#463).

• hook_purl() should not write the path of the R script to the output document (thanks, @fenguoerbian, #2348).
