No, it does not because of an extend option. Here is a picture (I've already included it in my previous mail): { "string ${var} string" } BBBBBBBBBBBBBBBBBBBBBBBBBB SSSSSSSSSSSSSS SS IIIIII B - Block region S - String region I - Identifier regionI got this information using synID function. > If I read ':help syn-keepend' right, then 'keepend' does not > allow a region on which it is used to have proper subregions. Except for 'extend' regions. That is why Block is 'keepend' and 'extend'.
What if 'extend' can override only the 'keepend' of only immediately enclosing region ? The example in :help syn-extend only has examlpe of overriding 'keepend' of immediately containing region. Does not say whether 'extend' acts all the way up the stack of enclosing regions. Yakov
