描述

I think it would be useful to print a diff when a tracked branch is updated. Current behaviour:

pkg> add BenchmarkTools#master

# change the master branch

pkg> up
[...]
  Updating `~/.julia/environments/v0.7/Project.toml`
 [6e4b80f9] ~ BenchmarkTools v0.2.5+ #master
  Updating `~/.julia/environments/v0.7/Manifest.toml`
 [6e4b80f9] ~  BenchmarkTools v0.2.5+ #master

which IMO would be better as

pkg> up
[...]
  Updating `~/.julia/environments/v0.7/Project.toml`
 [6e4b80f9] ↑ BenchmarkTools v0.2.5+ #master(commit1) ⇒ v0.2.5+ #master(commit2)
  Updating `~/.julia/environments/v0.7/Manifest.toml`
 [6e4b80f9] ↑ BenchmarkTools v0.2.5+ #master(commit1) ⇒ v0.2.5+ #master(commit2)

Additionally, perhaps we should always print the commit hash for tracked branches, e.g. st would change from

(v0.7) pkg> st
Status `~/.julia/environments/v0.7/Project.toml`
 [6e4b80f9] BenchmarkTools v0.2.5+ #master

to

(v0.7) pkg> st
Status `~/.julia/environments/v0.7/Project.toml`
 [6e4b80f9] BenchmarkTools v0.2.5+ #master(commit)

研究方向
Examine the display logic in Pkg.jl, specifically the functions that print package status and update information. Look for how tracked branches and commit hashes are currently handled. Investigate the possibility of fetching the previous commit hash before an update and displaying a diff. Consider any relevant issues or PRs that discuss similar enhancements.
