[Easytag-mailing] Tags always 'changed'

[Yang Zhang <yanghatespam gmail com>]

Hi, whenever I select a folder and tracks are listed in the middle pane, 
then switch to another folder or try to exit, EasyTag says there have 
been unsaved changes and prompts me to save the tracks, even though I 
have done nothing - it seems to ask me about all tracks.

After reading the docs, I find:

"Sometimes when loading files, you will note that some files are 
displayed to red. This will be due to useless spaces which are 
automatically stripped in the fields.  So it displays the file in red to 
let you to save the file. Note that you can't disable this feature)."

How do I tell exactly what changed?  I find it strange that nearly every 
single track has been auto-corrected, since these were auto-tagged by 
another program, Picard, which gets information from an online music 
database - did Picard really add extraneous spaces?

Also, why can't this feature be disabled?
