 In the code for handling the gohome command, the $homepage variable is not
 quoted when passed to the shell, which causes issues when a character
 handled by the shell is present in the homepage.  To see this, try {{{port
 gohome xdvipdfmx}}} and note that the page loaded has everything from the
 & to the end stripped.  To see a more catastrophic error, try {{{port
 gohome libksba}}} (at least until that port's homepage is corrected).
