[Gimp-docs] Error git push

[Kolbjørn Stuestøl <kolbjoern stuestoel no>]

I was trying to update my translation this night using git push, but get 
the error message
"remote: error: refname 'GIMP_HELP_2_8_2' is ambiguous".
"To ssh://[my_username]/git/gimp-help-2"

It's a long time since I pushed something to the translation, so perhaps 
I have forgotten something.
How and where do I set the correct refname?
