core: Check $TERM before setting columns with tput

It seems that Travis Linux containers no longer set `$TERM` as of today,
on top of not setting `$COLUMNS`, leading to failed builds despite all
of the tests passing.

From https://travis-ci.org/mbland/go-script-bash/jobs/174877408#L209-L212:

  $ bash ./go test
  tput: No value for $TERM and not -T specified
  fold: option requires an argument -- 'w'
  Try `fold --help' for more information

The test reproduces the issue and verifies the fix.
