New tab does not get activated
When opening new file pairs (in an existing meld instance) with "-n" (new tab) option, meld doesn't activate this new tab anymore but keeps the previously activated tab activated.
I usually use meld to check the differences of each file before committing it. Tabs and activating the latest tab simplify the process as one can check each file one after each other without opening lots of windows, include the current file in the change set or not while iterating over the files, and close meld and all tabs finally with a single click.
