Git does not warn about badly written whitespace

I've set config of git so that 'git config --list' gives following:

core.editor=vim
core.whitespace=trailing-s开发者_JAVA百科pace,space-before-tab,indent-with-non-tab
core.repositoryformatversion=0
core.filemode=false
core.bare=false
core.logallrefupdates=true

But when I want to commit a file whit trailing space or other whitespace problem, it never complains. Don't know what I can do.

For it to warn you during commit, I believe you have to write a pre-commit hook which will check for the appropriate whitespace and warn you.
