The setqflist() function sets the valid flag only for entries with a
valid file name and a line number. The other functions and commands that
populate the quickfix list do not apply this criteria. For these
commands/functions, as long as a quickfix errorformat pattern matches a
line, then the valid flag is set.
Changing this will break existing scripts (as can be seen from the failure
in the unit tests).
