Problem:

As a user, when I change the 'url' field in my repositories .gitmodules file to be relative, rather than absolute, the link to the associated submodule within the Bitbucket source view page is no longer active and is replaced by a text representation. Attached screenshots, and here is a diff as an example of the .gitmodules change to stimulate the issue:

#!diff

[submodule "communis"]
        path = communis
-       url = git@bitbucket.org:kanetoadstudios/communis.git
+       url = ../communis.git

Suggested solution:

Whatever parses the .gitmodules file, for the purposes of presenting the user with a link to the associated submodule, should be modified to understand relative paths and behave in the same way as it would if the 'url' field was absolute.
NOTE: If there is a problem resolving the relative link, the current operation is acceptable, but I don't believe there is a problem in the case I'm reporting as git performs a recursive clone quite happily with the relative url I supplied. See gitmodules documentation for info.
