[PATCH v6 0/3] gitweb: refactor If-Modified-Since handling

Changes since v5:
* Use `test_when_finished` to unset HTTP_IF_MODIFIED_SINCE.
* Actually use the tree ID in the `modification: tree snapshot` test.
* Conditional last_modified argument for `$cgi->header` git_snapshot
  and git_feed.
* tree-ish -> trees in git_snapshot commit message and test name.

Unchanged since v5:
* Patch 1/3, but I'm resending it anyway with `git send-email`.  I
  could skip resending it with:

    git send-email … HEAD^^

  but that would mess up the patch numbering.


W. Trevor King (3):
