SRU review: +1

It was quite painful to handle the quilt noise in revert-pcre2.patch and slowed down my review quite a bit to identify the real changes in there. I'd appreciate it if everyone could normalise their quilt refreshing in the future by using "-p ab --no-timestamps --no-index" or equivalent as recommended in https://wiki.debian.org/UsingQuilt please.
