Comment (by akimd):

 Hi Christopher,

 This failure has bugged me for a while now...  I'm not sure I understand
 its root, but the symptoms are precisely this trailing TAB in some tests
 for some users.  Let's nail it.

 The following tarballs contain a first fix, but maybe the following test
 cases will also fail, and I need your help.

 https://www.lrde.epita.fr/~akim/private/bison/bison-3.7.6.335-1d541.tar.gz
 https://www.lrde.epita.fr/~akim/private/bison/bison-3.7.6.335-1d541.tar.lz
 https://www.lrde.epita.fr/~akim/private/bison/bison-3.7.6.335-1d541.tar.xz

 Please after `configure` and `make`, run `make check-examples` and if
 there are failures, then look in
 `examples/c/bistromathic/bistromathic.test` for the corresponding call to
 `run`, and add `-t` as first argument to it.  Your logs show that we need
 it on line 318, so I did this:

 {{{

  sed -e 's/\\t/ /g' >input <<EOF

  EOF

 +run -t 0 '> (1+
  (       -       atan    cos     exp     ln      number  sin     sqrt
  > (1+
  > ''
 }}}

 Please tell me if more calls to `run` need that to get a passing test
 suite.

 Cheers!
