I confess I have not read the guidelines on making code contributions, 
so I don't know which step includes code review by general onlookers - 
so here's a quick code review of this change.

The proposed change is summarized as:

I'd regard that change as unsafe for the following reason.

Currently Apple have reached version 10 (i.e. "X") of MacOS, and version 
7 of IOS. I suspect these may merge in the future, and be named either 
simply "OS" or something like that. Now, given enough years, the version 
number will reach 50, i.e. in Roman numerals, "L" - and so be called 
"OSL". This could result in a false positive in the above test, since 
OSL is a substring spread across what are really two distinct parts of 

I'd therefore propose that this test should be something more like
    if the platform is among the items of "MacOS,Linux" then

However - I've not actually tested that, nor checked whether the itemDel 
can be safely assumed at that point in the script - so you should 
probably ignore this suggestion :-)
