if you have Python, here's an alternative;
Code:
flag = False
num=1 # renaming counter
for line in open("file"):
    line = line.strip()
    if line.startswith("M_I : ["): flag = True
    if flag:        
        l = line.split()    
        try:
            if l[0].isdigit():
                l[0]=str(num)
                num+=1                 
        except:pass
        print " ".join(l)
    else:print line
    if line.startswith("]"):
        flag = False

output:
Code:
# ./test.py

style

STYLE(1)						      General Commands Manual							  STYLE(1)

NAME

       style  -  analyze surface characteristics of a document

SYNOPSIS

       style [ -ml ] [ -mm ] [ -a ] [ -e ] [ -l num ] [ -r num ] [ -p ] [ -P ] file ...

DESCRIPTION

       Style  analyzes	the surface characteristics of the writing style of a document.  It reports on readability, sentence length and structure,
       word length and usage, verb type, and sentence openers.	Because style runs deroff before looking at  the  text,  formatting  header  files
       should  be  included  as part of the input.  The default macro package -ms may be overridden with the flag -mm.	The flag -ml, which causes
       deroff to skip lists, should be used if the document contains many lists of non-sentences.  The other options are used to locate  sentences
       with certain characteristics.

       -a     print all sentences with their length and readability index.

       -e     print all sentences that begin with an expletive.

       -p     print all sentences that contain a passive verb.

       -lnum  print all sentences longer than num.

       -rnum  print all sentences whose readability index is greater than num.

       -P     print parts of speech of the words in the document.

SEE ALSO

       deroff(1), diction(1)

BUGS

       Use of non-standard formatting macros may cause incorrect sentence breaks.
