I might have written the awk a bit differently, but working with what you've got, this should add the leading and trailing square brackets.

Code:
awk  -F "]" -v RS="["  '
        NR == 1 {                              # establish file name just once at beginning
                split( FILENAME, d, ".");
                outfile = d[1] "_out.txt";
                printf( "[" ) >outfile;         # opening bracket to the output
        }
        /\]/{                                   # for each record, print the last one if there, save this one
                if( last )
                        print last >outfile;    # print the one from the last time
                last = $1;                     # save this one til next record is read or end
        }
        END {
                printf( "%s]\n", last ) >outfile;       # print the last line of the matrix and closing bracket
        }
        ' $f

The logic is such that it saves the current line in the matrix and will output it as the next is read. At the end of the input file, the last line of the matrix is printed with the closing bracket.

makedbm(1M)						  System Administration Commands					       makedbm(1M)

NAME
makedbm - make a dbm file, or get a text file from a dbm file SYNOPSIS
makedbm [-b] [-l] [-s] [-E] [-i yp_input_file] [-o yp_output_name] [-d yp_domain_name] [-m yp_master_name] [-S delimiter] [-D num- ber_of_delimiters] infile outfile makedbm [-u dbmfilename] DESCRIPTION
The makedbm utility takes the infile and converts it to a pair of files in ndbm format (see ndbm(3C)), namely outfile.pag and outfile.dir. Each line of the input file is converted to a single dbm record. All characters up to the first TAB or SPACE form the key, and the rest of the line is the data. If a line ends with `' (backslash), the data for that record is continued on to the next line. makedbm does not treat `#' (pound-sign) as a special character. Because makedbm is mainly used in generating dbm files for the NIS name service, it generates a special entry with the key yp_last_modi- fied, which is the date of infile (or the current time, if infile is `-'). The entries that have keys with the prefix yp_ are interpreted by NIS server utilities. OPTIONS
The following options are supported: -b Insert the YP_INTERDOMAIN into the output. This key causes ypserv(1M) to use DNS for host name and address lookups for hosts not found in the maps. -d yp_domain_name Create a special entry with the key yp_domain_name. -D number_of delimiters Specify number_of_delimiters to skip before forming the key. -E Delimiters are escaped. -i yp_input_file Create a special entry with the key yp_input_file. -l Lower case. Convert the keys of the given map to lower case, so that, for example, host name matches succeed inde- pendent of upper or lower case distinctions. -m yp_master_name Create a special entry with the key yp_master_name. If no master host name is specified, yp_master_name is set to the local host name. -o yp_output_name Create a special entry with the key yp_output_name. -s Secure map. Accept connections from secure NIS networks only. -S delimiter Specify the delimiter to use instead of the default delimiter for forming the key. -u dbmfilename Undo a dbm file. Prints out the file in text format, one entry per line, with a single space separating keys from values. OPERANDS
The following operands are supported: infile Input file for makedbm. If infile is `-' (dash), the standard input is read. outfile One of two output files in ndbm format: outfile.pag and outfile.dir. ATTRIBUTES
