[Nix-dev] git-gui: require not using ttk

[David Guibert]

Hi,

I've try to launch git gui but it doesn't work:
$ git gui
Error in startup script: bad window path name ".git-gui-wrapped"
    while executing
"bind [winfo class .] <<ThemeChanged>> [list InitTheme]"
    (procedure "apply_config" line 36)
    invoked from within
"apply_config"
    (file
"/nix/store/swsb01j7j8i2z76cfmjfnrczr1p0a8sl-git-1.7.1/libexec/git-core/.git-gui-wrapped"
line 1154)

Without usettk, git gui starts
$ git config gui.usettk false

New to tcl, I don't know what's wrong in the following line
bind [winfo class .] <<ThemeChanged>> [list InitTheme]

Any idea?
