Re: Incorrect column positions with vertical splits

This happens when the linebreak setting is set, which causes Vim to
break the line at whitespace instead of in the middle of any word.

When I resize my terminal to 60 characters, and create the line
consisting of 40 'x', a space, 40 'x', the ruler displays 1,41 when my
cursor is on the space and 1,42-61 when my cursor is on the first 'x'
of the second word. I believe 42 is the byte offset of the character
under the cursor relative to the beginning of the line, whereas 61 is
the column of the cursor in the current line. Vim had to add 20 spaces
to pad the line, which explains why the cursor would be at column 61.

Is that not what you observe?

Best,
Mathias Rav
