[PATCH 2/2] Truncate the SHA1 part of the submodule name to 7 characters

From
Peter Collingbourne <peter@pcc.me.uk>

The rationale is that a submodule naming clash is a highly infrequent event (as compared to a file naming clash) so we can minimise the ugliness of generated submodule names by using a smaller number of characters.
