lynx-dev [PATCH to dev18] fix posting to news (when external editor is used)

[Vlad Harchev]

* Use (!isspace(c)) instead of (isgraph(c)) in LYNews.c:message_has_content,
  since former could treat characters not listed as "graph" in currently set
  locale as blank. In particular, this prevented posting messages with
  Cyrrillic letters only, when external editor is used (all cyrillic letters
  were treated as blank, so message was refused from posting by lynx since it
  "had no content") provided that russian locale was not set (setting proper 
  local could be impossible on some broken systems) -VH
  
 Best regards,
  -Vlad
