ensure everyone is OK with what's going on...
Constantly adjusting backwards ain't right ;)

Make <If> sections in virtual host context fill in cmd->path so that
other directive notice that they are in a config section.
    
This fixes LogLevel not working in <If> sections that are not in
Location/Directory/File sections.


Make ap_check_cmd_context() treat <If> sections like <File> sections.
This is necessary to properly disallow directives that don't work in
<If>.
    
A separate NOT_IN_IF flag may be nicer, but would create much more
hassle when being backported to 2.4.
