Custom ticket queries cosmetic fix, as a direct follow-up to r6569: reduce waste of vertical space. See #6674.

Testing: Merge [6619] from trunk

Increase delay in config test_reparse since fat filesystems have very low resolution on timestamps

When looking at ticket description diffs, I've noticed a strange "v1 vs. v1" comparison, as it should have been "Initial version vs. v1".

Turned out it was a bug in `Resource.__new__`, as I was not aware of the `0 == False` equality in Python.

Move docutils imports at the toplevel, as it seems that imports in methods can be problematic in some cases (e.g. see #4280).

In this specific case, the error seen was:
{{{

Thanks to H. Turgut Uyar for reporting the issue and testing the fix.

Testing: Merge through [6592] from trunk

Testing: Another tweak to try to cleanup the output on Windows, as suggested by Tim.

Testing: Merge through [6591] from trunk

Testing: Further Windows compatability cruft. Thanks again to Tim.

Fix for `WikiMacroBase` so that it will return the description correctly if an inherited macro uses non-ascii characters in docstring.

Closes #6890.
