Bug ID: 54234
           Summary: vbscript fails to compile when colon follows Else in
                    If...Else
           Product: Wine
           Version: 7.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: vbscript
          Assignee: wine-bugs@winehq.org
          Reporter: jsm174@gmail.com
      Distribution: ---
I just ran into a script where there is a ':' separator on a new line after an
ELSE:
if IsEmpty(BallData(idx).id) and aBall.VelY < -12 then 'if tip
hit with no collected data, do vel correction anyway
                        if PSlope(aBall.x, FlipperStart, 0, FlipperEnd, 1) >
1.1 then 'adjust plz
                                VelCoef = LinearEnvelope(5, VelocityIn,
VelocityOut)
                                if partialflipcoef < 1 then VelCoef =
PSlope(partialflipcoef, 0, 1, 1, VelCoef)
                                if Enabled then aBall.Velx =
aBall.Velx*VelCoef'VelCoef
                                if Enabled then aBall.Vely =
aBall.Vely*VelCoef'VelCoef
                        end if
                Else
 :                      VelCoef = LinearEnvelope(BallPos, VelocityIn,
VelocityOut)
                        if Enabled then aBall.Velx = aBall.Velx*VelCoef
                        if Enabled then aBall.Vely = aBall.Vely*VelCoef
                end if
I was able to fix this by changing:
Else_opt
    : /* empty */                           { $$ = NULL; }
    | tELSE NL StatementsNl_opt             { $$ = $3; }
    | tELSE StatementsNl_opt                { $$ = $2; }
to
Else_opt
    : /* empty */                           { $$ = NULL; }
    | tELSE StSep_opt StatementsNl_opt      { $$ = $3; }
    | tELSE StatementsNl_opt                { $$ = $2; }
