logmanoriginal 37f84196b7 [GooglePlusPostBridge] Fix title is empty if content is too short
The bridge would generate empty titles if the content is longer than
50 characters, but doesn't have further spaces in it. With this commit
the title is correctly generated based on the contents, taking missing
spaces into account.
