Shader Editing problem - compiled shader in editor

Ive been messing with shaders the past days, but I have run into the problem that when I save a shader and reopen it to edit it, I see the following... (or similar) this is not what I have put in.

Code (csharp):

1.     SubShader{
2.         Pass{
3.             Program "" {
4. // Vertex combos: 1, instructions: 7 to 7
5. // Fragment combos: 1, instructions: 2 to 2, texreads: 0 to 0
6. SubProgram "opengl " {
7. Keywords { }
8. Bind "vertex", Vertex
9. Bind "normal", Normal
10. "!!ARBvp1.0
11. # 7 instructions
12. PARAM c[5] = { { 0.5 },
13.         state.matrix.mvp };
14. TEMP R0;
15. DP4 R0.x, vertex.position, c[3];
16. MAD result.color.xyz, vertex.normal, c[0].x, c[0].x;
17. DP4 result.position.w, vertex.position, c[4];
18. MOV result.position.z, R0.x;
19. DP4 result.position.y, vertex.position, c[2];
20. DP4 result.position.x, vertex.position, c[1];
21. MOV result.fogcoord.x, R0;
22. END
23. # 7 instructions, 1 R-regs
24. "
