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):

*** bash-0.99/general.c	Wed May 24 21:16:07 1989
--- src-0.99/general.c	Fri Jun 16 15:22:59 1989

*** 293,297
    while (n--)
      {
!       if (*p == '/')
  	p--;
  

--- 293,297 -----
    while (n--)
      {
!       while (*p == '/')	/* skip multiple occurrences of '/' */
  	p--;
