Dominic proposed fixes/5.20.3/ which is fine by me assuming git-dpm
copes (I expect it does).

OK, I've had a quick look at these. They are all in 5.22.1 so fixed in
sid/stretch, no worries about that.

Here are a few things that caught my eye while at it. +1 from me to all
the others on the list.

d40f1ca59e9f4eb4e0e717b5304072636b24a62a lib/perl5db.pl: Restore noop lock prototype
  this is already in jessie as fixes/perldb-threads.diff

0f19268d11e0e7ce38b5a449f9f53461a0dc3226 [perl #123748] - Add test case for possible getenv/putenv/setenv stomping in perl.c (also squash 63209b393029691eb62065536b4aaab4ade1ad7b into it)
  This is not a functional change, just a new test. Do we want that?
  Also, I'm not sure if squashing is the right thing to do but I don't
  feel strongly about that.

8d89c0509dd5eb1de58dc6617f6e08599eb24792 [PATCH] [perl #123786] don't leak the temp utf8 copy of namep
  This is the only one that's not a cherry-pick from another branch so it's
  worth a mention, though it definitely needs to be included.
  The ticket says:
    "This isn't an issue in blead, since the leaking code is no longer present - all pad names are in utf-8 so there's no need to convert."
  Blead at the time (Feb 2015) was pre-5.22 so it should be OK on sid. I've
  verified that the test case leaks on jessie but not sid.

ccafce1bfd59cdbdd7af0ad68f7557a7471d6c64 Perl_save_re_context(): re-indent after last commit
  Whitespace only but would be nice to group with 17d9707d444517764c7bcb479c236a8c58a1d605
  Again, to squash or not to squash?

0cb29f21ba1db04416bb1a2dbc32cd5f7c75bc84 lib/h2ph.t to test generated t/_h2ph_pre.ph instead of the system one
  Another test-only commit. 

41575f0a39566008526e7e38eab84cba82cf372b Add pthread to libswanted
  This is not a doc fix though it was grouped there.
  We override libswanted in debian/prune_libs.diff so maybe not that useful?
