write_tree: suppress double-slash in blob HTML filename

When emitting a blob in the root tree of a commit, write_tree() composes
the blob's HTML filename with an extra slash before the "f=", like this:

    output/r/repo/b/master/t//f=README.txt.html

Although the double-slash is not harmful on Unix, it is unsightly, and
may be problematic for other platforms or filesystems which interpret
double-slash specially or disallow it. Therefore, suppress the extra
slash for blobs in the root tree.
