Dynamically allocate the buffer used for reading data from the input
handle and default to 64k instead of the 1k (BUFSIZ) static buffer.
This makes a large difference in performance of some applications.
Make the buffer size tunable from the command line.

Update example to use KiB per recent change to ../ftp/progressbar.c

Bump date for -e.

Apply patch from PR bin/28717
This adds a -e option to progress which causes the progress bar to be
sent to stderr. This allows using progress mid-pipe, such as:
tar -cf . | progress -e bzip -1c | ssh host "cat > file"

Support strsuftoll(3) suffixes for '-l length'.
Provide an example of copying raw disks using dd, with a progress bar.

-z actually passes the input file through gunzip(1).
Having an option to really pass it through gzip(1) would be nice...

Drop trailing whitespace.

Allow custom text printed before (left of) the progress bar from progress(1):

miyu# cat openoffice-linux-1.1.0.tgz | progress -z -p 'Bytes written: ' dd of=/dev/null bs=1m
Bytes written: 193 MB 13.83 MB/s 0+195211 records in
and:
miyu# progress -f openoffice-linux-1.1.0.tgz -z -p 'Bytes written: ' dd of=/dev/null bs=1m
Bytes written: 28% |****** | 57919 KB 14.12 MB/s 00:09 ETA

OK'd by lukem.

The correct capitalisation of 'NetBSD.org' is (you
guessed it) 'NetBSD.org'.

some mdoc fixes.

remove section name comments -- they're in the template.

branches: 1.3.2;
Remove second item in BUGS section; it is fixed in progress.c rev. 1.2.

use ftp(1) instead of lukemftp

progress(1) is a standalone version of lukemftp's progress bar
(pulled in via reachover makefile) suitable for measuring the
input to arbitrary pipes.
This is intended for use by sysinst.
