port 2.1.0 - progress count leads to excessive lines in output

[macintosh@…]

I'm running an automatic nightly update by having an update script as part of periodic daily.

The problem is, that the progress counts introduced in port 2.1.0

--->  Updating database of binaries: 100.0%
--->  Scanning binaries for linking errors: 100.0%

leads to an excessive amount of totally superflous lines in the log file periodic.daily.

The problem has been described in details in the groups:

Note that there is an implementation of isatty available, and defined in pextlib. It's called from at least one place inside the port command, and should probably be used here to qualify use of the eye-candy.

Patch against base to prevent the use of \r when stdout is not a tty
