I’m using reference style links in a document I’m working on, and I notice that some of the links end up with little red dashes under them.
For example, somewhere high in my document I have a line like this…
Quotations may also be imported from [www.WikiQuote.org][wikiq]
…and ‘wikiq’ has the little red dashes under it.
At the end of my document I have another line like this…
… and, again, ‘wikiq’ has little red dashes under it.
And yet, other reference style links don’t have such an indication.
What are the dashes trying to tell me?
