pathencode: for long paths, strip first 5 chars, not first dir When encoding long paths, the pure Python code strips the first directory from the path, while the native code currently strips the first 5 characters. This discrepancy has not been a problem so far, since we have not stored anything in directories other than data/. However, we will soon be storing submanifest revlogs in metadata/, so the discrepancy will have to go [1]. Since file collisions are avoided by the hashing alone (which is done on the full unencoded path), it doesn't really matter whether we drop the first dir, the first 5 characters, or special-case non-data/. To avoid touching the C code, let's always strip the first 5 characters. [1] Or maybe elsewhere, but the discrepancy is ugly either way.
