can BBEdit be scripted to distill it to:

where the number at each line start is the count...
If you don't mind plain ol' vanilla, you could do it with AppleScript's text
item delimiters - something like this:
==========================
to countIdenticalLines from l
set c to {}
set d to ASCII character 1
set text item delimiters to return
set l to l's text items 1 thru -2
set text item delimiters to d & d
set l to d & l & d
repeat until (count l) is 0
set text item delimiters to d
set w to l's text item 2
set text item delimiters to d & w & d
set l to l's text items
set c's end to ((count l) - 1 as string) & ": " & w
set text item delimiters to ""
set l to l as string
end repeat
set text item delimiters to return
set c to (c as string) & return
set text item delimiters to {""}
c
end countIdenticalLines
set x to "123456789
abcdefgh
123456789
opqrstuv
123456789
abcdefgh
dsltcpip
abcdefgh
123456789
abcdefgh
123456789
opqrstuv
abcdefgh
123456789
opqrstuv
opqrstuv
"
countIdenticalLines from x
==========================
--> "6: 123456789
--> 5: abcdefgh
--> 4: opqrstuv
--> 1: dsltcpip
--> "
Such a routine avoids the need to iterate through every individual line. In
the above case, for example, the loop repeats only 4 times (once for each
unique occurrence of a string).
