Subject: [PATCH] Issue #133 - ever increasing indent! This is a simple but
 profound change in pprint.c. Since leading space is preserved on script code,
 after tidy indents the code once, a second run on that tidied file would add
 more indent to already indented code. This fix should be carefully checked,
 and removed if there are other bad consequences. Bump the version point to 4
 for this change.
