Here is the output of "danmero" code. Works great,, This is easier for me to understand..
Dan how would you trim spaces that could be suffixed using your approach? Even though I did not mention this requirement earlier. That is where I want to take this,, so that my code would not break even if users make common mistakes..
Here is the output of "Franklin52". You must be a mind reader too..apart from being great at scripting :-).
It meets my requirement of removing spaces at the end of line too.. I think, that could sometimes break code if users make typos with input files.
I would really appreciate if you could explain how the above command works. I am getting little dizzy with it..
Thanks in advance !..

Since suffix spaces in my input.txt file got removed,, in my previous post,, I am posting it again..

erl_comment_scan
erl_comment_scan(3erl) Erlang Module Definition erl_comment_scan(3erl)NAME
erl_comment_scan - Functions for reading comment lines from Erlang source code.
DESCRIPTION
Functions for reading comment lines from Erlang source code.
DATA TYPES
comment() = {integer(), integer(), integer(), [string()]} :
EXPORTS
file(FileName::filename() (see module file)) -> [Comment]
Types Comment = {Line, Column, Indentation, Text}
Line = integer()
Column = integer()
Indentation = integer()
Text = [string()]
Extracts comments from an Erlang source code file. Returns a list of entries representing multi-line comments, listed in order of
increasing line-numbers. For each entry, Text is a list of strings representing the consecutive comment lines in top-down order; the
strings contain all characters following (but not including) the first comment-introducing % character on the line, up to (but not
including) the line-terminating newline.
Furthermore, Line is the line number and Column the left column of the comment (i.e., the column of the comment-introducing % char-
acter). Indent is the indentation (or padding), measured in character positions between the last non-whitespace character before the
comment (or the left margin), and the left column of the comment. Line and Column are always positive integers, and Indentation is a
nonnegative integer.
Evaluation exits with reason {read, Reason} if a read error occurred, where Reason is an atom corresponding to a Posix error code;
see the module file(3erl) for details.
join_lines(Lines::[CommentLine]) -> [Comment]
Types CommentLine = {Line, Column, Indent, string()}
Line = integer()
Column = integer()
Indent = integer()
Comment = {Line, Column, Indent, Text}
Text = [string()]
Joins individual comment lines into multi-line comments. The input is a list of entries representing individual comment lines, in
order of decreasing line-numbers ; see scan_lines/1 for details. The result is a list of entries representing multi-line comments,
still listed in order of decreasing line-numbers , but where for each entry, Text is a list of consecutive comment lines in order of
increasing line-numbers (i.e., top-down).
See also: scan_lines/1 .
scan_lines(Text::string()) -> [CommentLine]
Types CommentLine = {Line, Column, Indent, Text}
Line = integer()
Column = integer()
Indent = integer()
Text = string()
Extracts individual comment lines from a source code string. Returns a list of comment lines found in the text, listed in order of
decreasing line-numbers, i.e., the last comment line in the input is first in the resulting list. Text is a single string, contain-
ing all characters following (but not including) the first comment-introducing % character on the line, up to (but not including)
the line-terminating newline. For details on Line , Column and Indent , see file/1 .
string(Text::string()) -> [Comment]
Types Comment = {Line, Column, Indentation, Text}
Line = integer()
Column = integer()
Indentation = integer()
Text = [string()]
Extracts comments from a string containing Erlang source code. Except for reading directly from a string, the behaviour is the same
as for file/1 .
