We are trying to desing special fits ingesters for moving headers content into a 
database system when we encounter the following case:

CARD    = 'data 2.5' '  / 10 '

This card (I just type in the worst case we could imagine) has no comment but how to detect
that. It seams that each case we have with a single quote following a slash will create an
ambigous situation. Is there any solution to this?. 

We have checked within the standard FITS document and haven't found anything which will 
remove this ambiguity.

Is this a recommended FITS entry?  I would have thought that you wanted either:

CARD    = 'data 2.5''  / 10 '

or

CARD    = 'data 2.5'' ''  / 10 '

Quote characters inside character strings are supposed to be doubled to signal
that the string doesn't end there--that should remove the ambiguity.
