Proposed merges (reformatted):
| We could merge in these additional small changes that are on trunk:
|
|      - Add new "use_7z yes" port option to allow distfiles in 7z
|        format (#18521, ryandesign)
|
|      - port lint no longer requires variable master_sites if the port
|        has no distfiles (#18479, ryandesign)
|
|      - Upgrade will no longer accept ports that are not installed
|        (but it still installs new ports as dependencies if needed).
|        In particular, this means that "port upgrade all" will no
|        longer proceed to install every available port. (jmr in
|        r46052)
|
|      - Add mkdtemp Tcl command to create temporary directories.
|        (#17181, perry)


There were no real objections.
Ryan, would you take care of merging them?
