No, I want to preserve the 'spa ces' in the inline string.


The code I have posted is suppose to output
"pre\n1\n   space\n3\npost\n"

Your suggested code outputs:
"pre\n1\nspace\n3\npost\n"


Space isn't preserved.. I think you have misunderstood my proposal ;-)

Good idea as long its spaces. I wonder how tabs can be handled properly.
Should tabs be converted to 8 spaces?  Should tabs be sliced?
