+Do not add horizontal tab characters to any file in Bison's repository
+except where required.  For example, do not use tabs to format C code.
+However, make files, ChangeLog, and some regular expressions require
+tabs.  Also, test cases might need to contain tabs to check that Bison
+properly processes tabs in its input.
