The at mentions functionality does not work when the username is followed by a full stop

[kwerri]

Repro steps:

1. Get a username of a user on a site that uses BuddyPress. Let's call this username.

2. Make a comment on a post, including the text @username. (i.e. the at sign followed by username followed by a full stop.

3. Observe that the username is not converted into a link to the user's BuddyPress profile.

The problem seems to be with the regex pattern that is used to determine at-mentions in posts. This is in the bp_activity_find_mentions functions in wp-content/plugins/buddypress/bp-activity/bp-activity-functions.php

The pattern is /[@]+([A-Za-z0-9-_\.@]+)/, but it should be /[@]+([A-Za-z0-9-_\.@]+[A-Za-z0-9-_@])/

See #3721.

This is fixed in trunk. Can you ​test the fix and see if it works for you?
