I wonder if this is a larger bug in the text system? I was going to suggest
just inserting the Unicode character "zero-width no-break space" (U+FEFF)
after the slash, but when I tried it (in TextEdit) I got the very phenomenon
you describe - the break occurs before "delete", not after.
I was able to solve the problem, though, by also inserting a "zero-width
space" (U+200B) before the slash... So there's a solution for you, but it
seems unnecessarily elaborate. m.
