[PATCH 2/2] t0030: Add tests with consecutive text lines and others with spaces added.

[PATCH 2/2] t0030: Add tests with consecutive text lines and others with spaces added.

[Carlos Rica]

Previous tests only had paragraphs of one line. This commit adds some
tests to check when many consecutive text lines are given.

Also, it adds tests for checking that many lines between paragraphs are
correctly reduced to one when there are tabs and spaces in those lines.

   These were used in the development of the new in-place version
   of the stripspace function, which acts on a buffer instead
   on file descriptors. The first version I wrote passed the
   previous tests but it was completely broken in these cases.
