Test: libcrmcommon: Test characters after %N
in pcmktime_format_hr() unit tests. The parsing logic in
pcmktime_format_hr() is hard to follow. For a little while, I was
confused and thought it would give incorrect output if there were any
format specifiers after a "%N".
There is probably no real use case for this support, but it should work
(and currently it does work).
