The close link on the mobile site gets mangled if you vote to close something that has existing close votes:
This is a result of the response handler in
StackExchange.vote_closingAndFlagging which does
b.text(b.text().replace(/\w?\(\d\)/, "") + " " + d.Message)
Since the mobile version of the site doesn't generate a space between the "close" and "(#)" portions, the
\w? matches the "e" in addition to the count and cuts it off.
The mobile version of the site should likely have a space before the vote count, and the intended regular expression was probably
/\s?\(\d\)/ (although removing the extra space isn't strictly necessary).
