Enclose $line in quotes:
echo "$line"
And is
$(echo ${#line})
really what you meant to do? If $line is 10 characters long, you're going to end up with the variable $10, which will give an error. Just use the one part to return the length of the line:
${#line}

I was trying to remove the blank from beginning of a line.
when I try:
sed 's/^ +//' filename
it does not work

But I think the first command should have also replaced any line with one or more blanks.

NAME
ColorData, GSData, MobilityData, MoveData, VoidData - Data subclasses for storing common undo information
SYNOPSIS
#include <Unidraw/Commands/datas.h>
DESCRIPTION
The Unidraw library predefines several Data subclasses for storing common undo information: ColorData stores two PSColors (usually repre-
senting foreground and background colors), while GSData stores a complete set of graphics state in a FullGraphic object. MobilityData
stores the mobility and graphics state information needed to undo a change in mobility. MoveData stores a horizontal and vertical distance.
VoidData stores a void pointer as a useful alternative to deriving trivially from Data just to store one word of information.
COLORDATA PUBLIC OPERATIONS
ColorData(PSColor*, PSColor*)
Create a ColorData instance, supplying the PSColor objects it stores.
GSDATA PUBLIC OPERATIONS
GSData(Graphic*)
Create a GSData instance, supplying the Graphic object from which to copy a complete set of graphics state. The GSData constructor
copies this information into its _gs member, from whence it can be retrieved later.
MOBILITYDATA PUBLIC OPERATIONS
MobilityData(Mobility, Graphic*)
Create a MobilityData instance, supplying the mobility and a Graphic object from which to copy a complete set of graphics state.
The MobilityData constructor copies the graphic into its _gs member, from whence it can be retrieved later.
MOVEDATA PUBLIC OPERATIONS
MoveData(float, float)
Create a MoveData instance, supplying two floating point numbers that normally represent horizontal and vertical movement.
VOIDDATA PUBLIC OPERATIONS
VoidData(void*)
Create a VoidData instance, supplying a pointer to an object of unknown type.
