bug#13059: frame-title does not update modified toggle on tmpfs

[Yi Wang]

It sounds strange.

For me, this problem never happened on obscure then re-expose windows. 

On the other hand, tmpfs should not be the reason either. The modified mark fail to update at everywhere *except* for files in the home directory or subdirectories of $HOME. For example, I tried /tmp, /var/tmp, a file outside $HOME (while have edit permission), and use root to edit a file at /. At all those positions I had this problem.

Best wishes,

Yi

Does this happen only for tmpfs volumes?

If you obscure the frame with some other window of another
application, and then re-expose it again, does the modification
indication gets updated?
