I would consider this as a bug, not an incident. The behaviour is different from what the open command does for overwriting files. There an N skips only the file you're asked for and proceeds.

With commit the N breaks the whole commit. A checkin with a CR/LF text file and a binary file commits none of them if N is answered for the text file.
I also get an error message:

D:/Daten/Projects/Privat/SharpFossil/Test/testdir/3.txt contains CR/NL line endings; commit anyhow (y/N/a)?
