Bugfix: initial slash + quote only needs one additional slash on match at start when writing

If the object or content group begins with any number of slashes followed by a single or double quite, only a single slash is needed to delimit the quote.
This is done because no valid object or content group can start with a slash and expected to be treated as if it were quoted.
That means the quote is meaningless.
The initial slash delimit is necessary in case the object name starts with a single or double quote but it should not be treated as such.
This for an object name of " would be written as \".
