gnupg/kbx/keybox-defs.h
Werner Koch b008274afd Nuked almost all trailing white space. 
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces.  In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much.  For future commits the pre-commit scripts
checks that this won't happen again.
