Phil Estes b1527e0a10 Handle progress line length properly for formatting ...

Two issues with a prior PR for handling line-spanning progress bars are
fixed in this PR:
 - corner case where output line len == term width: extra line was being
 added
 - line length calculation was including escape characters causing
 calculations to span lines when output was still only on one line
