Request for better syntax checking in lang.opt

[Thomas Koenig]

Hi,

having just lost a few hours on a space in lang.opt where
there was supposed to be none, leading to a new option
being silently ignored, a request:

Would it be possible to improve the syntax checking for lang.opt?
It's a file that people touch only rarely, so it is likely that
they will have no experience or will already have forgotten the
gotchas they encountered the last time.

Regards
