Right on both counts. The sample Git hooks in 
.git/hooks/pre-commit.sample check for trailing white space, because it 
makes the output of 'git diff' fragile in email etc., and I'm following 
this lead in my own Git repository.

tzdb 'make check_white_space' does something similar, for similar 
reasons. It currently has an exception for leap-seconds.list, which I'd 
rather remove.
