Yes, it does match. Which is why it's not moving into the else branch. But without a matching group it doesn't know what to put into $1, so it just prints an empty line.
I am using GnuWin32 sed and am having trouble with the regexp - i.e., they don't behave the same way as in UNIX (POSIX and and all that). I have a stream of data, e.g.:
11111'222?'22'33?'333'44444'55555'
I want to insert a \n after those apostrophes that are *not* preceded by a ?.

number::compare5.18
Number::Compare(3) User Contributed Perl Documentation Number::Compare(3)NAME
Number::Compare - numeric comparisons
SYNOPSIS
Number::Compare->new(">1Ki")->test(1025); # is 1025 > 1024
my $c = Number::Compare->new(">1M");
$c->(1_200_000); # slightly terser invocation
DESCRIPTION
Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested again.
Now this would be very pointless, if Number::Compare didn't understand magnitudes.
The target value may use magnitudes of kilobytes ("k", "ki"), megabytes ("m", "mi"), or gigabytes ("g", "gi"). Those suffixed with an "i"
use the appropriate 2**n version in accordance with the IEC standard: http://physics.nist.gov/cuu/Units/binary.html
METHODS
->new( $test )
Returns a new object that compares the specified test.
->test( $value )
A longhanded version of $compare->( $value ). Predates blessed subroutine reference implementation.
->parse_to_perl( $test )
Returns a perl code fragment equivalent to the test.
