Title: add -L option for pwd to avoid side effects

I have added -L option to pwd command.
I can avoid side effects when pwd is an alias to pwd -P.

According to pwd doc :
If `-L' and `-P' are both given, the last one takes precedence. If
neither option is given, then this implementation uses `-P' as the
default unless the `POSIXLY_CORRECT' environment variable is set.
