Details:

This issue has been discussed before:
https://bbs.archlinux.org/viewtopic.php?id=108640

Copy mode and “hardcopy -h” always begin at the start of the scrollback
buffer. If a user sets a large scrollback limit with little output, then copy
mode and the file written by “hardcopy -h” will begin with many blank
lines before the first line of output.

The attached patch limits the scrollback buffer traversal to begin at the
first line of output, instead of the beginning of the scrollback buffer.

Also, code for moving to %age of buffer is changed to use float division so
that two different rep_cnt will not jump to the same location, except for
buffers less than 100 lines. Previously, the computed line number is rounded
down to the nearest 100th due to integer division.
