pwd has the -L option:
The following options shall be supported by the implementation:
-L
If the PWD environment variable contains an absolute pathname
of the current directory and the pathname does not contain any
components that are dot or dot-dot, pwd shall write this
pathname to standard output, except that if the PWD environment
variable is longer than {PATH_MAX} bytes including the
terminating null, it is unspecified whether pwd writes this
pathname to standard output or behaves as if the -P option had
been specified. Otherwise, the -L option shall behave as the -P
option.
It mentions "dot-dot" and "dot".
It does seems to allow:
(cd /; PWD=////////// pwd -L)
//////////
and
(cd /home/casper; PWD=/home///////casper pwd -L)
/home///////casper
Is this a correct implmentation?
Is it *required* for the implementation to behave this way?
