SVN 557 adds a new test to testdata/testinput5. The test result depends
on the newline setting. It fails if PCRE2 is compiled with a newline
default other than the standard 0xA.
To make the test work, testinput5 needs the following line at the
beginning of the file, like it is already present in most other test files:
#newline_default lf any anycrlf
My testing shows that other tests in testinput5 are not affected by this
change.
