Summary0000787: Bug With Rows or Cell Limit (perhaps)
Description

I noticed that modules sometimes get truncated. Saving a module with 127 channels and 1,024 rows causes the warning about reaching the file limit and truncates the data to 505 (512 - 7) rows. How ever, the Impulse Tracker Project format handled a module with 1,024 channels and 65,536 rows with no problems.

Steps To Reproduce
  1. Create a new Impulse Tracker or OpenMPT module.
  2. Increase the channel quantity to 127 and the row quantity to 1,024.
  3. Using Find and Replace, fill all cells with data.
  4. Save the module.
    At this point, you should be informed / warned that your pattern will lose data.
  5. Reopen the module.
  6. Navigate to raw 505.
    You should notice that this row and the rows below it contain no data.

The compressed pattern data may not exceed 65535 bytes. This is exactly why the warning is shown.
