After indenting a piece of code all modified lines have 0x0A only end-of-line characters.
I found this out when Visual SourceSafe indicated these files as being different and I was unable to find these differences. Examining the files with a hex-editor revealed that the line-ends were modified. All unmodified lines still ended with 0x0D and 0x0A.
The above also applies to code inserted from templates (ie entity block).
