I keep expecting 'sigspace' to have something to do signatures.
So do I. How about :litspace for 'literal space'? Except they aren't
exactly literal, because they only indicate where _some_ space has to
be, not that it has to be exactly that sort of space.
What about :gappy, to indicate that there have to be gaps in the source
text at the points where there are gaps in the pattern?
Or, to borrow a word from a different artistic pursuit, 'negative
space'. "Negative space is the space between objects or parts of an
object, or around it."
Or, perhaps contextualize the concept to computers as "nullspace".
