 subject: profile stores empty string values without double quotes
 tags: pullup
 
         prof_parse.c (need_double_quotes):
         The profile library will happily read in right hand values
         that represent the empty string by parsing "".  However,
         when storing the same empty string back to a file, the 
         empty string is written without the double quotes.
 
         This means that
 
                 [section] foo = ""
 
         becomes
 
                 [section] foo =
 
         which is invalid input.  A subsequent attempt to parse the
         profile will result in an invalid input error.  
 
         KFW and KFM's realm editors can inadvertently produce an 
         invalid krb5 profile if one of the ignored sections of the
         input profile contains a right hand value that is "".
 
         This patch was produced by Asanka Herath and it was reviewed
         by jaltman and lxs.
