I’ve implemented and used a lisp-based line-wrapping feature for a while and it’s still sub-optimal for me. I now want to try to explore if I can add it directly to redisplay. 

Here is what I come up with: in redisplay code, instead of only checking for whitespace, check for a ‘no-wrap text-property, if the character has this property, don’t wrap before[1] this character (or maybe it can be the opposite, only wrap when the character has a ‘can-wrap property). And this text property is calculated and applied once. 

Could this be plausible? Is checking text property is fast enough for redisplay?

[1] There are some complications to this, some characters can’t have line break before them, some can’t have after; maybe  use ‘before, ‘after and nil instead of binary value.
