reimplement vi0 and helper functions so that they are likely faster (vi0 bring cursor to start of current line; before, this was done by checking each character in the string backwards, but now it is done by looking at the line metadata, which is faster for us by some constant factor)

fix bug in '^' motion: only move cursor if (chr = /home/humza/Downloads/sml/shf/fcore/cursor.sml' '), not if Char.isSpace (which also returns true if chr is newline or tab) is true

add just one more 'word' test, extract steps to delete from search list into a reusable function (don't need to memorise the steps), and fix bug in cursor.sml where we were looking at tl without calculating correct strIdx

in cursor.sml's 'helpTillPrevChr' function, properly handle edge case where graphical chr is followed by multiple line breaks

amend cursor.sml's 'helpTillNextChr' function to work with new line break scheme, and use it to implement 'delete till' functionality starting with 'dt' (for example, 'dta' deletes till 'a', 'dts'detetes till 's', etc.)

fix very minor issue in cursor.sml's 'helpViL' function (previously returned cursorIdx when non-line breaks is followed by non-line break, but now return cursorIdx + 1 instead which is the correct behaviour, because we want to move the cursor rightwards one position in that case

|
new task: rewrite basic cursor.sml functions (h, j, k, l) to look for 'is line break preceded by non-line break?' rather than 'is there a double line break?' because the second question which is already implemented has buggy behaviour on triple line breaks, where cursor does not go to the place user expects. Currently, on Cursor.viL has been rewritten to match the first question.
