Well I don't think that anybody else has send a few thouthent C++ source
files thru Get_Line.

As you might know: The main part of AdaCL is a text filter framework. Mainly
used for C++ source-file refactoring. When it comes to string handling and
Text_IO I have seen it all - event he most esoteric bugs.

I used the AdaCL text filters for more the a month before I noticed the
first file which did not have a last line any more. The bug is indeed very
sparce - bit it did happen in actual use.

So
