How to ignore space when using 'git send-email' command

Hi,

I am using git version 1.6.1.

When i use 'git send-email' command how can I specify it to 'ignore-all-space'? I see there is an 'ignore-all-space' option in 'git diff' and 'git format-patch', but there is not such option for git send-email.

I have already commit my changes to my local branch, so I can't use 'git diff' , 'git format-patch' to display the different which ignore white spaces.

Can you please tell me how can I send-email which ignore white-spaces?

Thank you.
