Accommodate for pu having been renamed to seen

This patch series adjusts Git's own source code to reflect that change.

Please note that even with these patches, there are still a couple places where pu is used:

* In the translations. These are legitimate words in languages that are not English (as in "gpg n'a pas pu signer les données" where "pu" is French for the English "could").
* In upload-pack.c, where a variable named pu is short form for "pack-objects updates".

Changes since v2:

* One accidental quoting change in v1 was reverted.

* Rebased onto maint (no merge conflicts, so it does not actually change anything).

Changes since v1:

* Rebased onto master (no conflicts, so it is safe, and it is more robust than basing the patches on seen which already contains v1 of these patches).

* Adjusted the quoting to match
