In git_tree, rename $base variable (which is passed as $basedir
argument to git_print_tree_entry) to $basedir. Do not esc_html
$basedir, as it is part of file_name ('f') argument in link and not
printed. Add '/' at the end only if $basedir is not empty (it is empty
for top directory) and doesn't end in '/' already.
