Subject: gitk: Failure of new tabbed preferences dialog
Message-ID: <4F749C71.7050201@ramsay1.demon.co.uk>

Hi Pat,

I just tried the new gitk (master @fae9d76) and, since I don't have
themed widgets, the preferences menu item uses the emulated tabbed
dialog code, which fails like so:

    can't read "col": no such variable
    can't read "col": no such variable
        (reading value of variable to increment)
        invoked from within
    "incr col"
        (procedure "doprefs" line 36)
        invoked from within
    "doprefs"
        (menu invoke)

I tried the following (maybe *too* obvious) fix:

-- >8 --
diff --git a/gitk-git/gitk b/gitk-git/gitk
index 651b740..68cd1a1 100755

+    set col 0
     foreach {page title} $pages {
 	if {$use_notebook} {
 	    $notebook add $page -text $title

which seems to work.
