There are some problems with a number of spaces on travis: it differs. Cannot
use the same code as for fish because output looks like
{prompt}{spaces}^[0m ^[[{number}D
and both `{spaces}` and `{number}` differ on my machine and in travis.
This commit strips CRs from *.ok files and test output. Test failure used to be
not recognized due to pipe: `cat -v` always succeeds meaning that `if ! diff
… | cat -v` always succeeds too.
