With Perl 5.26.0, 5.26.1 and 5.27.1, a few of the tests for $SPLIT in SpreadSheetPluginTestCases fail like this:

Expected SPLIT
`<ul> <li> $SPLIT(, Apple Orange Kiwi)=\|Apple, Orange, Kiwi\| </li> <li> $SPLIT(-, Apple-Orange-Kiwi)=\|Apple, Orange, Kiwi\| </li> <li> $SPLIT([-:]$sp*, Apple-Orange: Kiwi)=\|Apple, Orange, Kiwi\| </li> <li> $SPLIT($empty, Apple)=\|A, p, p, l, e\| </li> <li>`
$SPLIT(x)=\|\|
$SPLIT(x)=\|*\|
`</li> <li>`
$SPLIT()=\|\|
$SPLIT()=\|*\|
`</li> </ul>`

After some debugging I came to the conclusion that the behaviour of Perl 5.26 is broken and have filed a bug report (https://rt.perl.org/Public/Bug/Display.html?id=132334). Nevertheless, an alternative fix in TWiki is both simple and harmless and should be released.

Investigation by the Perl Porters revealed that this is not about the Perl version. Instead, any non-threaded installation of Perl has this bug, whereas the threaded Perls are fine. I was mislead because I use Debian's vanilla Perl (which is threaded) for 5.20 and 5.24 but built the "newer" versions as unthreaded Perl. I've modified the summary accordingly.

In any case, removing the /o modifier is an appropriate fix (coming soon).
