Customizing bibliography author names from the bst file

Question

I'm using this bibliography style from this question. What I like about it is that it (almost) doesn't show the initials of the authors, which is what I'm looking for. However, if the reference has only one author it does show the initials. Also, if the reference has two authors I want it to be displayed as Author1 & Author2 in the Reference list (paragraph in this case).

To fix this, I edited the bst file, specifically FUNCTION {format.names} in line 396, so that

1. if reference has more than 2 authors, it'll be displayed as Author1 et al.
2. if reference has 2 authors, it'll be displayed as Author1 & Author2
3. if reference has 1 author, it'll be displayed as Author1
4. in all cases without initials.

this is the edited function:

FUNCTION {format.names}
{ 's :=
  #1 'nameptr :=                
  s num.names$ 'numnames :=     
  numnames 'namesleft :=        
    { namesleft #0 > }
    { s nameptr "{vv~}{ll}{, jj}" format.name$ 
    't :=
numnames #2 >
    {
      nameptr #1 >
        {
          nameptr #2 =
            {
              " {et~al.}" *
            }
            {
                nameptr #2 >
                { "" * }
                { ", " * t * }
                if$
            }
            if$
    }
    't
  if$
}
{
  nameptr #1 >
    {
      namesleft #1 >
        { ", " * t * }
        {
          numnames #2 >
            { "," * }
            'skip$
          if$
          s nameptr "{ll}" format.name$ duplicate$ "others" =
            { 't := }
            { pop$ }
          if$
          t "others" =
            {
              " {et~al.}" *
            }
            { " \& " * t * }
          if$
        }
      if$
    }
    't
  if$
} if$

  nameptr #1 + 'nameptr :=
  namesleft #1 - 'namesleft :=
}

while$
}

This works well but, in cases 2 and 3 above, there is a point (.) at the end of the author

Here is a MWE taken from the question linked above.
