Thanks everyone for the assistance. In case anyone else has this problem, here was my solution:
1. Dokuwiki wants just LF as the newline character, not CR/LF. These were changed after a copy involving an FTP copy from one Windows server to another. So the task at hand is to remove just the CR from the .txt files.
2. Since this is for a Windows OS, I used a tool from Stahlworks Technology (

3. Made a backup of the "pages" directory and ran "remcr" against the original dirs.
4. Spot checked the files, looked good! :-)
