[PATCH] gitk: Fix nextfile() and more

[OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>]

Hi,

The current nextfile() jumps to last hunk, but I think this is not
intention, probably, it's forgetting to add "break;". Right?  And this
patch also adds prevfile(), it jumps to previous hunk.

The following part is just my favorite the key-binds, it doesn't matter.

+    bind . <Control-p> "$ctext yview scroll -1 units"
+    bind . <Control-n> "$ctext yview scroll 1 units"
+    bind . <Alt-v> "$ctext yview scroll -1 pages"
+    bind . <Control-v> "$ctext yview scroll 1 pages"
+    bindkey P prevfile
+    bindkey N nextfile

What do you think of this?

Thanks.
