I think all the proposals up to now will lose the fixed width property which the requestor needed to keep, esp. if you just add a "0" in front of $2 the record size is gone.
Not sure, though, how to do it. Break it into lines with fmt, modify with awk or sed, remove <linefeed> with tr?
Were there single lines, this might work:
Code:
$ sed 's:\(^THIS[^ ]*  \) :\10:' file

FOLD(1) 						    BSD General Commands Manual 						   FOLD(1)

NAME
fold -- fold long lines for finite width output device SYNOPSIS
fold [-bs] [-w width] [file ...] DESCRIPTION
The fold utility is a filter which folds the contents of the specified files, or the standard input if no files are specified, breaking the lines to have a maximum of 80 columns. The options are as follows: -b Count width in bytes rather than column positions. -s Fold line after the last blank character within the first width column positions (or bytes). -w width Specify a line width to use instead of the default 80 columns. The width value should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before using fold. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of fold as described in environ(7). SEE ALSO
expand(1), fmt(1) STANDARDS
The fold utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). BUGS
If underlining (see ul(1)) is present it may be messed up by folding. BSD
