check-code: allow 'Except EClass as variable:' Python 2.4 compatibility has been dropped.

check-code: allow print and exec as a function This is required to move forward on python3 compatibility.

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.

util.h: kill no longer needed definitions for Python < 2.5 see e1fb276d4619

rebase: add short -k option for --keep histedit and strip already have a short option for keep, so this makes the interface more consistent

revset: test current behavior of addset class The addset class isn't simple and it has a hidden bug that will be fixed by future patches. So let's test the current behavior.

revset: remove duplicated definition of choice() from addset._iterordered() choice() is already defined before val1 = None. Perhaps there was merge or rebase error.
