Creating a scalar ref directly off substr() seemed to be causing
the underlying non-ref scalar to end up in Perl's scratchpad.
Assign the substr result to a local variable seems sufficient to
prevent multi-megabyte SVs from lingering indefinitely when a
read-only daemon serves rare, oversized blobs.

Patch 2 helps lei users avoid wasting bandwidth.

I've been running patches 6 and 7 on https://yhbt.net/lore/
for a while, now; and memory use seems far lower.

The rest are pretty minor things, I think.

Eric Wong (7):
  lei: always pass $lei to LeiAuth->op_merge
  lei export-kw: skip read-only IMAP folders
  shared_kv: remove cache_size attribute support
  http: use a larger buffer for ->getline responses
  listener: emit warnings on EPERM
  thread: avoid Perl5 internal scratchpad target cache
  git: avoid Perl5 internal scratchpad target cache
