The large majority of other files uses plain LF.

Some test resources and some forceQualifierUpdate.txt files also use
CR-LF as line endings. These files are left unchanged.

NewWizardMessage.properties and NewTypeWizardPage.java even used mixed
line endings; most lines using plain LF, but a few using CR-LF. These
are normalized to LF only.
