Compare with file in rounds may not honor checked options

[srjfoo]

In a recent testing session of the DP Post-Processing Workbench (ppwb), I was testing the option to compare the post-processing text as downloaded from a project page (CTF is Concatenated Text File).

Under "If comparing with a file from the rounds", I checked all three options (remove proofreaders' notes, regroup split words, silence formatting diffs), with "best effort" selected.

Please note that I did not do exhaustive testing, but I found that:

• There were split words in the output
• There was inline markup in the output
• There were proofers' notes in the output.

The other thing that I found confusing was that the display showed trailing spaces in the output where the sources had none.

The attached zip contains my most recent test pair. Some of the <sc> tags had the problem, some did not.

Since I'm not an active PPer, I'm not entirely sure what I should be seeing, so I may be seeing problems where there are none. Let me know if there's further testing you'd like me to do.
