The Debian packaging of pcre2 is maintained in git, using the merging
workflow described in dgit-maint-merge(7).  There isn't a patch
queue that can be represented as a quilt series.

A detailed breakdown of the changes is available from their
canonical representation - git commits in the packaging repository.
For example, to see the changes made by the Debian maintainer in
the first upload of upstream version 1.2.3, you could use:

    % git clone https://git.dgit.debian.org/pcre2
    % cd pcre2
    % git log --oneline 1.2.3..debian/1.2.3-1 -- . ':!debian'

(If you have dgit, use `dgit clone pcre2`, rather than plain `git
clone`.)
