in thread Do nothing? or Do something important in a very obscure way?

Actually, that's exactly what I thought it meant, hence the "Do nothing?" in the title.

I remember the days when I used to be obliged to put blocks of NOP's into my assembler subroutines (we used a ratio of 1::20 active instructions) to allow space for remedial patching of the executable, but I couldn't see why you would add them to a regex!

What's this about a "crooked mitre"? I'm good at woodwork!

    There is no reason to be adding them to a regex. It is simply due to the way the double colon works that postfixing it to a nongreedy match turns the match into a NOP, which is what TheDamian was mentioning in the Exegesis.
