Currently realsync gets caught in a loop when trying to copy over files that exceed the limit for file path/name length. What happens it realysync fails to copy the file, as expected. But then realsync, noticing that this file is in the source but not the destination, tries to copy the file over again so that source and destination are properly synced. Realsync is unable to copy the file over due to the file path/name length again and the cycle repeats.
The changes in this pull request allow realsync to fail gracefully when the file path/name is too long without trying to copy the file again.
