- fixed issue RT#130344: false warning "operator in print statement"
for "use lib".

- fixed issue RT#130304: standard error output should include filename.
When perltidy error messages are directed to the standard error output
with -se or --standard-error-output, the message lines now have a prefix
'filename:' for clarification in case multiple files
are processed, where 'filename' is the name of the input file. If
input is from the standard input the displayed filename is '',
and if it is from a data structure then displayed filename
is ''.

- implement issue RT#130425: check mode. A new flag '--assert-tidy'
will cause an error message if the output script is not identical to
the input script. For completeness, the opposite flag '--assert-untidy'
has also been added. The next item, RT#130297, insures that the script
will exit with a non-zero exit flag if the assertion fails.

- fixed issue RT#130297; the perltidy script now exits with a nonzero exit
status if it wrote to the standard error output. Prevously only fatal
run errors produced a non-zero exit flag. Now, even non-fatal messages
requested with the -w flag will cause a non-zero exit flag. The exit
flag now has these values:

0 = no errors
1 = perltidy could not run to completion due to errors
2 = perltidy ran to completion with error messages

- added warning message for RT#130008, which warns of conflicting input
parameters -iob and -bom or -boc.

- fixed RT#129850; concerning a space between a closing block brace and
opening bracket or brace, as occurs before the '[' in this line:

my @addunix = map { File::Spec::Unix->catfile( @ROOT, @$_ ) } ['b'];

Formerly, any space was removed. Now it is optional, and the output will
follow the input.

- fixed issue git#13, needless trailing whitespace in error message

- fixed issue git#9: if the -ce (--cuddled-else) flag is used,
do not try to form new one line blocks for a block type
specified with -cbl, particularly map, sort, grep

- iteration speedup for unchanged code. Previously, when iterations were
requested, at least two formatting passes were made. Now just a single pass
is made if the formatted code is identical to the input code.

- some improved vertical alignments
