[wdiff-bugs] wdiff-1.0.1 bug report: test suite test 3 (use pager) erroneous test failure

[John Purnell]

In file ./tests/wdiff.at line 196 there is a sed substitution to
globally remove "\r" to work around the screen bug. Unfortunately this
replaces all occurrences of "r" in the file screenlog.0 resulting in
the test failing as can be seen in the contents of
./tests/testsuite.dir/3/testsuite.log:

---

So "Pager" becomes "Page", "start" becomes "stat", and "printed"
becomes "pinted".
