[PATCH] mod_include and cwd

[Marc Slemko <ma...@znep.com>]

I think this was introduced when we got rid of the getwd() from
mod_include.c.  I think the below is the easiest way of fixing it.

Can be demonstrated with the following SSI (/~marcs/inc/t.html):

<!--#include virtual="/~marcs/incl.html" -->
XXX
<!--#exec cmd="/bin/sh -c pwd"-->
XXX

where /~marcs/incl.html is also parsed by mod_include.  Without the patch,
pwd gives gives ~marcs/public_html/ instead of ~marcs/public_html/inc/.  

I think this is the only place the cwd is messed with in mod_include.

See PR#742.  So wonderfully rare to see a PR that is about a bug that I
almost wept in joy...
