hotlist: broken new entries if old-style path is present

[slavazanko]

Steps to reproduce:

• try to replace your ~/.config/mc/hotlist by:

  ENTRY "old-style-url" URL "/#sh:root@myserver.ru:C/var/www/site.ru/htdocs"
  

• run mc, press ctrl+\ (call hotlist)
• add current directory to hotlist
• see content of your ~/.config/mc/hotlist

expected result: should be new entry with path to current directory

actual result: few random bytes here (looks like as pointer data)
