Bug#818240: checkbashisms: should warn about test -nt and -ot

[Benjamin Moody]

Package: devscripts
Version: 2.15.3
Severity: normal

Dear Maintainer,

The '-nt' and '-ot' options to the 'test' or '[' command are not
standardized by POSIX.  These options are implemented by both bash and
dash, but their behavior differs between the two shells in regard to
nonexistent files (see the wontfix'ed bug #558989).

Thus, checkbashisms should warn about the use of these options.
