git merge problem

["Коньков Евгений" <kes@reg.ru>]

Hi

I have started branch from master
then on master were changes in whitespace (code formatting)
in branch on that lines changes were not.

Now when I try to merge branch to master I get lost changes at space on master
So I try to ignore space change

git merge -Xignore-space-change my_branch
 I have lost formatting in master.

I wanna to give priority to changes on branch master:
git merge -Xours my_branch

and now also no results: I get old space formatting which were on
branch master before starting my_branch

Please tell me, how can I fix that problem?
# git --version
git version 1.8.1.5

as you see on branch master right formatting will be replaced by wrong
formatting on branch new_function_find

as I have said: doing #git merge -Xignore-space-change new_finction_find
no result :_-((

the wrong formatting on branch new_function_find are old formatting
that were in branch master, before branch new_function_find were started
no changes were made to that line on branch new_function_find

while on branch new_function_find all new changes from master
were merged as:
#git merge -s recursive -Xignore-space-change master

please help
