Convert Spaces To Tabs Not For Code

What is the best way to format source code examples? It seems that indentation is ruined when some user chooses to edit using ConvertSpacesToTabs. Currently, I use (1 + 4 * N) spaces for indentation (N is the level of indentation). I had even more problems with my usual (3 * N). Using Tabs+Space seems too deep and is cumbersome to do without a handy tool.

 IndentationTestFunction4p1() { /* what I would like to have e.g. */
     for(int i=0; i<8; i++) {
         for(int j=0; j<8; j++) {
             if(i>j) {
                 if(i+j>8) {
                     /* */  
                 }
             } 
         }
     }
 } 

 IndentationTestFunction4p1() { /* ruined */
for(int i=0; i<8; i++) {
 for(int j=0; j<8; j++) {
if(i>j) {
 if(i+j>8) {
/* */  
 }
} 
 }
}
 } 

IndentationTestFunction3() { /* ruined */

for(int i=0; i<8; i++) {
for(int j=0; j<8; j++) {
 if(i>j) {
if(i+j>8) {
/* */
}
 } 
}
}

}

IndentationTestFunctionTabsPure() {

for(int i=0; i<8; i++) {
for(int j=0; j<8; j++) {
if(i>j) {
if(i+j>8) {
/* */  
}
} 
}
}

}

 IndentationTestFunctionSpaceTabs() {
 for(int i=0; i<8; i++) {
 for(int j=0; j<8; j++) {
 if(i>j) {
 if(i+j>8) {
 /* */  
 }
 } 
 }
 }
 } 

 IndentationTestFunctionTabsSpace() {
 for(int i=0; i<8; i++) {
 for(int j=0; j<8; j++) {
 if(i>j) {
 if(i+j>8) {
 /* */  
 }
 } 
 }
 }
 }

It would be nice to be able to use some trick, such as a prefix character (after initial space), to disable ConvertSpacesToTabs (i.e. spaces in preformatted lines should not be converted. I could see a standard being 1 or 2 spaces, followed by a line number, followed by whatever indentation you choose. Unfortunately, Wiki currently changes spaces on all lines.

Hear, hear!
