Issue #390 - fix indent with --hide-endtags yes.

Browse source 
The problem was, with --hide-endtags yes, a conditional pprint buffer
flush had nothing to flush, thus the indent was not adjusted.

To track down this bug added a lot of MSVC Debug code, but is only
existing if some additional items defined, so has no effect on the release
code.

This, what feels like a good fix, was first reported about 12 years ago by
@OlafvdSpek in SF Bugs 563. Hopefully finally closed.
