git-gui: textconv not used on unstaged files

Hi,

i am using a textconv filter to display .doc files as plain text. It seems git gui does not use this textconv filter for displaying new unstaged files (other files? = _O) It seems diff.tcl start_show_diff calls show_other_diff because of this. This manually loads the file and does not care about textconv filters.

Is this manual loading really necessary or can't we just ask git? If it is can it be modified to use the textconv filter?

Thanks, Greetings Peter

.gitattributes: *.doc diff=astextplain

gitconfig:
[diff "astextplain"]
     textconv = astextplain
