Subject: Revert "t0081 (line-buffer): add buffering tests"

This (morally) reverts commit d280f68313eecb8b3838c70641a246382d5e5343,
which added some tests that are a pain to maintain and are not likely
to find bugs in git.

 test_description="Test the svn importer's input handling routines.
 
-These tests exercise the line_buffer library, but their real purpose
-is to check the assumptions that library makes of the platform's input
-routines.  Processes engaged in bi-directional communication would
-hang if fread or fgets is too greedy.
+These tests provide some simple checks that the line_buffer API
+behaves as advertised.
 
 While at it, check that input of newlines and null bytes are handled
 correctly.
