handle later iniparser version assigning a zero length string value for 'key='
older iniparser versions ( like that used in upstream samba ) ignore 'key='
entries, the key is not entered into the dictionary at all. Later
versions of iniparse specifically handle the following special cases
* key=
* key=;
* key=#
by assigning a value of "" ( a zero length string ) to the key
in the dictionary.
