progress implementing 'PersistentVector.merge' for case where left subtree and right subtree have same depth

|
fix calculation of number to decrement by in 'PersistentVector.delete', after additional test showed that calculation resulted in incorrect metadata. (Todo: just implement function to merge left and right subtrees.)

add function to decrement persistent-vector.sml. (The plan is to split the left and right, and then decrement the right metadata so that the absolute indices match.)

|
fix another size-recalculation mistake in 'PersistentVector.splitRight' function. (When we are splitting in the middle of a BRANCH, we want to subtract the old child size from the remainder, and then add the new child size to the remainder, because this calculation will account for the splitting of preceding elements.)
|

|
e52d4856ee
|
amend recalculation of size metadata in 'PersistentVector.splitRIght: we always want to decrement by prevSize in this function. (We will have another function call to decrement so that left split and right split represent the same absolute indices when they are joined, before they are split.)

persistent-vector.sml was in a partial state where some functions use rope-like metadata and some functions do not, so change 'nextMatch' function to use rope-like metatadata (still need to change other functions)

fix bug in 'NormalYank.yankRight' function. Instead of calling 'Int.max (endOfLineIdx, high)', we should call 'Int.min (endOfLineIdx, high)' because we are trying to get the smaller number, and not the largest.

when deleting inside pair, instead of searching either for either chr1 or chr2 and stopping at first match, search instead for openChr and closeChr, and keep an integer tracking what level of nesting we are at. This gives us the behaviour we want, which is to delete the pair at the correct level of nesting. When we encounter openChr, we increment the nesting counter by 1 and continue searching. When we encounter closeChr, if the nesting counter is 0, we return the current index, but if the nesting counter is higher than 0 when encounter closeChr, we decrement the nesting counter by 1 and continue searching.

reimplement '/home/humza/Downloads/sml/shf/todo.md' motion so that it has the same behaviour as Vim. (If the cursor is not at a pair character, then check after the cursor to see if we find a pair-character there. If some location after the cursor has a pair-character, then move the cursor to it and find the pair of the character, if any.)
