Re: Patch: allow /./ and /../ in URL paths

Hi.

I fiddled a bit with your patch, and it is now more or less in the new 
beta. (1.6b7), although the implemtation is a bit different.

I took the liberty of slightly changing the semantics because I want to be 
able to back-port this to 1.5 without breaking existing configurations.

To this end, the /./ /../ (and //) smashing must be explicitly enabled in 
the configuration file via the SanitizePath directive. If you do not set 
this, mathopd will treat URLs with /./ etc as an error.

Also URLs that end with /. and /.. are not allowed. (As they were with the 
original patch.) It could be argued that one should make some attempt to 
'fix' these too, but that would be a bit messy. Perhaps someone has any 
more thoughts to this?

If no problems turn up I will probably release a new 1.5 version sometime 
next week.

Cheers
Michiel
