Check in meets_constraint

[bgiebl]

Why is in the meets_constraint() function the constraint only checked if it starts with the value of data_path and not for equality?

This leads to a problem for example for a dataset with a dimension with the name 'time' and with a variable with the name 't'
(commonly used for temperature).
If there is now a DODS request with the constraint string 'time' then meets_constraint will also be true for the variable 't'.
So the values of 't' will also appear in the response.
Is there a reason why it is not checked for equality in this line?
And is there a way to fix this behaviour?
