Problem:
Descriptions of plugins often contain taglinks which are generally
concealed. This misaligns them by 2 characters with descriptions that
don't have a taglink in them.
Solution:
Don't count "bar" characters (`|`) for the description width.
Example:
Actual buffer content:
```
myplugin.txt |lsp| is cool
myplugin.txt this is a nice plugin
```
Rendered as:
```
myplugin.txt lsp is cool
myplugin.txt this is a nice plugin
```
