Subject: vim-patch:9.0.2022: getmousepos() returns wrong index for TAB char
 (#25636)

Problem:  When clicking in the middle of a TAB, getmousepos() returns
          the column of the next char instead of the TAB.
Solution: Break out of the loop when the vcol to find is inside current
          char. Fix invalid memory access when calling virtcol2col() on
          an empty line.

closes: vim/vim#13321
