Comment 11 for bug 154145

(In reply to comment #10)
Thanks for clear test result. I now understand difference between "|-A.B.C." and "|-A.B.C. (the folder is empty)" in comment #0.
"Rebuild Index" process looks to be invoked during restart. It seems that I expected too much...

I think there is two ways for ILLEGAL_FOLDER_CHARS_AS_LAST_LETTER "." issue:
 1)MS Win only "ending dot" for compatibility on Linux & Mac OS X.
   (When MS Win, no problem because folder of "ending dot" was impossible.)
   In this case, compatibilty between Linux/Mac and Win is lost,
   then several users will complain when they will move mail folders.
 2)Keep current patch for compatibility among OS's and for ease of maintenance.
   This means design change, then action for incompatibility is required.
   e.g. Explanation in release notes, automatic file name change logic.
And I feel 1) is better.
