Ok, one of us is confused, and I think it's you. :-) Different OS's
use and expect different line endings for text files. Specifically:

Unix and Mac OS X: \n
Dos/Windows:       \r\n
Classic Mac OS:    \r

You said you were transferring files *from* a Mac *to* a PC. So I
assumed your files had \n line endings, and you used a converter to
add a \r before each \n, once the files were on the PC. But you're
saying that using TextEdit and TextWrangler on the Mac, the files
already get \r\n line endings, which is what the PC expects. So no
conversion should be necessary when transferring them to a PC. And
this is suspicious anyway, because I would expect TextEdit and
TextWrangler to use unix line endings by default, so you would have to
have manually changed the preferences to use PC line endings.

If you were going *from* a PC *to* a Mac (or Linux or other Unix),
then you would want a converter to delete all the \r characters from
each \r\n pair. Note I said *delete*, but you say your program
replaces each \r with a blank, thus not changing the file size. So in
effect each line gets an extra blank at the end.

So, in summary:
- If you're transferring a text file *to* a PC, you want to then
ensure that each line ends with \r\n.
- If you're transferring a text file *to* a Mac, you want to then
ensure that each line ends with \n.
- And if you're doing a conversion that strips the \r from each \r\n
pair, you want to delete the \r, not replace it with a blank.
