diff --no-index: reset temporary buffer lengths on directory iteration
Commit 875b91b3 (diff --no-index: use strbuf for temporary pathnames, 2012-04-25) introduced a regression when using diff --no-index with directories. When iterating through a directory, the switch to strbuf from heap-allocated char arrays caused paths to form like 'dir/file1', 'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected. Avoid this by resetting the paths variables to their original length before each iteration.
