Bug#93696: include command's search path is broken

[Jamie Heilman <jamie@audible.transient.net>]

Package: chpp
Version: 0.3.4-1

>From the documentation:

 - Command: include FILENAME
     Includes the file FILENAME. If FILENAME is relative, it is first
     searched for in the directory of the including file, then in the
     directories contained in the include search path (*note Invoking
     chpp::.).  If the file is not found, an error message is produced.

>From real life usage:

 Lets say I have a file named example.chpp which contains the command
 #include /etc/gdefs.conf

$ cat example.chpp | strace chpp
...
open("/usr/lib/chpp/include//etc/gdefs.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
open(".//etc/gdefs.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/etc/gdefs.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
...

Not only is that not the documented search path, the fact that an absolute
path was given is completely ignored.  If the included file has a relative
path the search path doesn't change, it still looks in
/usr/lib/chpp/include first, then in the local directory.
