Thomas Orozco 82df66ffe9 lfs: avoid accidentally quadratic performance in download path
Summary:
Currently, hg's lfs extension used bytes concatenation to download a response
from the server-side. However, concatenating bytes in Python can be
inefficient, since it'll re-allocate the whole thing and copy it every time you
concatenate.

This makes repeated concatenation O(N^2) on the number of things you
concatenate, which is undesirable. This diff updates hg's lfs extension to not
do that.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
