Subject: [PATCH] makepkg: Pass --stream to `hg clone` when creating the
working copy
Without --stream, `hg clone` reencodes+recompresses the entire repository,
to the storage settings of the host. But download_hg() already did that
on the initial network clone, and it is 100% pointless duplicated work for
the local clone.
The work that this saves is CPU-bound (not disk-bound), and is restricted
to a single core.
The --stream flag has only existed since Mercurial 4.4 (2017-11-01). Prior
to that, it was named --uncompressed. --uncompressed still exists as a
compatibility alias for --stream, and marked deprecated, though there is
currently no schedule for its removal.
