Fixes: #215
This also changes the behavior with spans including a CRLF line-ending.
Before the panic bug was introduced, these were rendered with the CRLF
being two visual columns wide. Now, any span extending past the EOL is
treated as including one extra visual column.

Tabs are always expanded to spaces by the graphical handler, and `tab_width` now defaults to 4. Instead of replacing every tab with a fixed number of spaces, spaces are used to align to the next tabstop. `tab_width` controls the space between tabstops rather than the fixed width of each tab character.
