Merged revisions 59005-59040 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk I've tried to fix test_cmd_line_script but I wasn't able to get all tests right. Nick, can you please have a look? ........ r59020 | facundo.batista | 2007-11-16 19:04:14 +0100 (Fri, 16 Nov 2007) | 12 lines Now in find, rfind, index, and rindex, you can use None as defaults, as usual with slicing (both with str and unicode strings). This fixes issue 1259. For str only the stringobject.c file was modified. But for unicode, I needed to repeat in the four functions a lot of code, so created a new function that does part of the job for them (and placed it in find.h, following a suggestion of Barry). Also added tests for this behaviour. ........ r59021 | facundo.batista | 2007-11-16 19:41:24 +0100 (Fri, 16 Nov 2007) | 4 lines Fix for stupid error (I need to remember to do a full 'make clean + make' cycle before the tests...).
