maint: remove all trailing white space

First, run this command:
  git grep -l '	 $'|xargs perl -pi -e 's/[ \t]+$//'
Then some minor fix-up to make the two newly-failing tests
pass once again:
* testsuite/mac-mf.sed: Append this, s/ $//,
to eliminate trailing spaces in the actual output.
* testsuite/y-newline.good: Manually remove a trailing
space between two concatenated prompts.
