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

# 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
