Allow FileAttachment.file to store longer file paths.
Review Request #4394 — Created Aug. 5, 2013 and submitted
Allow FileAttachment.file to store longer file paths. FileField, by default, limits to 100 characters, which was barely enough as it was. With the new change for prepending a hash, this was suffocating. We now set that max length to 512 characters. While that's far smaller than the max path length of most file systems, it should be enough for our use, and is far more than what users have had in the past.
Verified that the column had a max length of 512 after evolving.
