Ticket 47446 - logconv.pl memory continually grows

Bug Description:  Running logconv.pl without any special options
                  continually consumes more memory.

Fix Description:  The last fix introduced the use of regex matches which
                  caused the value of $1 to become undefined.  When using
                  all of the logconv cmd line switches, many undefined
                  variable warnings were printed.  This fix saves the value
                  of $1 in a local variable so that it it not undefined by
                  the use of subsequent regex matches.
