It's permitted to put multiple /'s between components in a path name
(and something I tend to do since file completion adds then to the end
of directories and I'm not yet used to that).  Cd, with "..", however,
get's confused by this.
	$ cd /usr/local//src
	$ pwd
	/usr/local/src
	$ cd ../..
	$ pwd
	/usr/local

Here's a quick look at what happens after I fix it; a one-line diff for
general.c follows (note that I have aliased pwd to "echo $PWD"; this
makes no difference).

cwns5$ echo $SHLVL
2
cwns5$ cd /usr/homes/chet/src/Shells/bash////Rt-AOS/
cwns5$ pwd
/usr/homes/chet/src/Shells/bash////Rt-AOS
cwns5$ cd ../..
cwns5$ pwd
/usr/homes/chet/src/Shells/bash//
cwns5$ cd Rt-AOS/
cwns5$ ./bash
cwns5$ echo $SHLVL
3
cwns5$ cd /usr/homes/chet/src/Shells/bash////Rt-AOS/
cwns5$ pwd
/usr/homes/chet/src/Shells/bash////Rt-AOS
cwns5$ cd ../..
cwns5$ pwd
/usr/homes/chet/src/Shells
cwns5$ 

Here's the fix (your line numbers may vary; I've made other changes):

      {
!       while (*p == '/')	/* skip multiple occurrences of '/' */
  	p--;
