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.

Problem: screenpos() wrong result with w_skipcol and cpoptions+=n
Solution: Use adjust_plines_for_skipcol() instead of subtracting
w_skipcol.

Problem: missing winid argument for virtcol()
Solution: Add a {winid} argument to virtcol()
Other functions col(), charcol() and virtcol2col() support a {winid}
argument, so it makes sense for virtcol() to also support than.
Also add test for virtcol2col() with 'showbreak' and {winid}.

Solution: Only add filler lines when appropriate. Also don't add the
'smoothscroll' marker when w_skipcol is zero. (closesvim/vim#12485,

easier to document.
