[MITgcm-support] Bug in rdmds.m when loading multiple record files

I noticed a bug in rdmds.m under MITgcm/utils/matlab, which only affects
the multiple-record files.
The problem comes from line 149:
allfiles=dir( sprintf('%s*.meta',fname) );
For example, when one wants to load A=rdmds('T', 'rec', 1), it actually
will look up all variables starting with
'T', including 'Ttave' etc. This is particularly problematic if there
are user defined output variables, e.g.,
if one wants to use variable name 'TSK' (surface temperature in this
example). Because the function
"localrdmds" in rdmds is called within the j=1, size(allfiles,1) loop
(line 157), the desired variable "T"
will be partially or entirely overwritten by "TSK" depending on the size
Moving "*" right before "meta" can easily address the issue without
affecting other functionality:
allfiles=dir( sprintf('%s.*meta',fname) );
Hope this helps.
