* src/variable.c (lookup_variable_for_file): New function to retrieve a variable assignment in a file context. * src/variable.h (lookup_variable_for_file): Declare it. * src/job.c (construct_command_argv): Look up .SHELLFLAGS. If .POSIX is set and we're using the default value, choose -c if we're ignoring errors else choose -ec. (construct_command_argv_internal): Ditto. * tests/scripts/targets/POSIX: Add tests.
