626	Change to check_multifile prevents (or complicates) use of single-record forcing files	m.hadfield	arango	"For a long time now it has been my practice to specify time-independent variables in forcing files by means of a single-record netCDF variable at zero time. For example:

{{{
netcdf roms_frc_dqdsst {
dimensions:
        time_fixed = 1 ;
variables:
        float time_fixed(time_fixed) ;
        float dQdSST(time_fixed) ;
                dQdSST:time = ""time_fixed"" ;
                dQdSST:long_name = "" surface net heat flux sensitivity to SST"" ;
                dQdSST:units = ""Watt metre^-2 Celsius^-1"" ;

// global attributes:
                :type = ""ROMS forcing file"" ;
}
}}}

In ticket 622 an extra check was added to check_multifile.F as follows:

''Improved check_multifile.F to report when the input data time records from NetCDF files is not enough to finish the simulation. Persisting the last available data record is not possible in ROMS. Users need to provide enough data to cover the simulation period from start to finish. Many thanks to Kate Hedstrom for bringing this to my attention. 
''

This prevents the above usage. Is this intended? Should the check be bypassed for single-record netCDF variables?
