When posting, users have access to shortened URLs for questions (e.g.
http://stackoverflow.com/q/7498413/117870) and also answers (e.g.
http://stackoverflow.com/a/27171218/117870). These can be very useful when posting links in comments.
If, however, one desires to link to another comment, there appears to be no shortened URL. Thus, users have to contend with links like this
These can sometimes be very long and can fairly quickly eat up the character allocation in comments.
I would like to know if there is any way of getting a shortened URL for comments posted across the Stack Exchange sites.
