I think we should keep the filetype name at "C". Adding variables to
specify what kind of C is fine, but using "c89" and "c99" as a filetype
name will cause trouble (you would need to triple all plugins that are
related to C).
There might be a way in between: when 'filetype' is set to "c89" or
"c99" an autocommand or plugin sets the global variable and sets
'filetype' to "c". I haven't seen this used yet, there might very well
be some disadvantages. At least it would be possible to set the
filetype in a modeline.
