[BUG] comments in grafts file broken in current master

While looking at allowing empty lines in grafts files, I discovered
that comments had already been implemented.  However, current
git-read-tree segfaults when there is a comment line in info/grafts:

dwitch@gandelf:/export/work/yann/git/git$ cat .git/info/grafts 
c118c026e44f02c3dbad00d924285eef2340f700
# foo
dwitch@gandelf:/export/work/yann/git/git$ git-read-tree master
Segmentation fault


The commit introducing the problem is
5040f17eba15504bad66b14a645bddd9b015ebb7 (blame -S <ancestry-file>),
which changes quite some things in the grafts area.
    

BTW, after segfaulting, .git/index.lock is still there, and the
"unable to create new cachefile" is not so helpful - I had to strace
to see what was happenning.

Hope this helps,
