[PATCH] Fix saving of multiple modified files on quit

[Peter Tyser <ptyser gmail com>]

Previously, file modifications could be lost when quitting meld
when multiple diff panes were open and more than 1 of the panes
had file modifications.  Quitting would prompt the user to
Discard/Cancel/Save the changes in one of the modified panes.  Pressing
"Discard Changes" would result in Meld quitting immediately without
prompting the user if they wanted to save the other modified files.

This issue only occurred if multiple diff panes were open, eg when using
Meld to diff/modify multiple files in a version-controlled directory.
