[PATCH] Make git-apply --stat less butt-ugly with long filenames

[PATCH] Make git-apply --stat less butt-ugly with long filenames

When git-apply was printing out long filenames, it used to just truncate
them to show the last "max_len" characters of the filename. Which can be
really quite ugly (note the two filenames that have just been silently
truncated from the beginning - it looks even worse when there are lots
of them, like there were in the current v2.6.13-rc4 cris arch update):

With this patch it now looks like so:

ie we've made it clear with an ellipsis that we've cut off something from
the beginning, and it also tries to do it cleanly at a subdirectory level.
