Keybase proof

I hereby claim:

• I am peff on github.
• I am peff (https://keybase.io/peff) on keybase.
• I have a public key ASBUTdmbqRWiZXxKC56hC7t8_6Mvdb5_gs-53B3u9hFoqAo

To claim this, I am signing this object:

# Generate a listing of all paths ever used in the repository, along with the
# disk space used by the path throughout the entire history.  Note that sizes
# for trees are cumulative; they include the sizes of all of the paths below
# them, in addition to the tree storage itself. All sizes are in bytes, and
# reflect git's delta and zlib compression.
#
# One caveat is that this is just the _current_ on-disk size. The on-disk size
# of each object may change if git repacks and chooses different delta bases,

This repository has a very large number of refs, which shows some slow-down on certain git operations.

#!/bin/sh

# Turn a file/line combination into a link to github.com.
# I use this from vim with:
#
#   command! Link :exec "!ghpath %:p " . line(".")
#
# Running ":Link" anywhere will get you a link to the current file and
# line number. Remember to drop this as "ghpath" into your PATH, and
# to turn on the executable bit.

This is a repository that has been packed over time with "git gc", but repacks from ~245M to ~145M with "git gc --aggressive". To narrow it down, I tried different packing options. With each of the following commands, I get these resulting pack sizes:

• git repack -ad: 246M
• git repack -ad -f: 376M
• git repack -ad --window=250: 246M
• git repack -ad -f --window=250: 145M
