'git format-patch --summary' seems to be turning off the stat

[Kaartic Sivaraam]

The documentation for "--summary" option in the format-patch Doc states, 
--summary Output a condensed summary of extended header information such 
as creations, renames and mode changes. It doesn't state anything about 
turning of the stat. Why does the stat get turned off when "--summary" 
option is used along with "git format-patch" ? Note: I do see that 
"--summary" is a diff-option but does that mean we should't be printing 
stat information in the patch when the user didn't mention "--no-stat"? 
Yeah, "git format-patch <ref> --summary --stat" does bring back the 
stat. --- Kaartic
