file and folder names garbled if too long in "save to disk".

[irfan ali khan]

using the 'save to disk' feature, with this protocol:

{authors}/{Series}/{series_index:0>2s|Vol | - }{pubdate:0>2s|| - }{title}/{title}

If the title/author names are long, the folder and filenames become oddly truncated. There is allowance for 255 characters in file names in ext4 and btrfs.

Example Book details:
title: Dealing: Or, the Berkeley-To-Boston Forty-Brick Lost-Bag Blues
author: Michael Crichton & Douglas Crichton & Michael Douglas
series: The Med School Years Series #1

total characters = 147.

folder structure looks like this:
Michael Crichton & Michael Douglas
Med School Years Series, The
Vol 01 - 2013 - Dealing_ Or, theoston Forty-Brick Lost-Bag Blues
Dealing_ Or, the Berkeley-Forty-Brick Lost-Bag Blues.epub

which altogether is 183 characters. i believe only the longest file/folder name needs to be less than 255 characters, (if that is what is causing this garbling/truncation)

That would be this line:
Vol 01 - 2013 - Dealing: Or, the Berkeley-To-Boston Forty-Brick Lost-Bag Blues
which is still only 79 characters.

This has been a very useful feature for me to output the folders in a format where folders = metadata for databaseing. hopefully this bug can be resolved, thank you so much in advance! enjoying calibre, very convenient tool!
