compoundMeter - how to get lilypond to recognize the bar line in the middle

[Jay Vara]

>I am not top-posting

I am using a compoundMeter - 5/4 + 2/4. I would like to see a bar line 
after 5 quarter notes (and after 7 quarter notes). Plus I would like 
Completion_heads_engraver to recognize the bar line after the 5 quarter 
notes.

I was able to artificially achieve getting the bar lines by adding a 
silent voice with those bar lines.

However I was not able to find anything that would make the fifth note 
g2 in the following example to be automatically replaced by g4~g4 [tied 
quarter notes] as happens for the seventh note where a2 is replaced by 
a4~a4.

Also, in the code below, I tried to prevent the time signature from 
printing - does not seem to work for compoundMeter. Also not sure why I 
got a couple of extra staff lines, plus how it got the 7/4 meter for the 
extra staves.

\version "2.18.2"
fooBar = { s1 s4\bar "!"  s2 \bar "||" }
music =  \relative c' {c4 d e f g2 a b4 c c b a g2 f4 e d c b a g a b}
\score {
  
  <<
   \override Staff.TimeSignature #'stencil = ##f 
   \compoundMeter #'((5 4) (2 4) )
    \set Timing.beatStructure = #'(5  2 )
   
    \new Voice = "theBarLines" { \fooBar \fooBar \bar "|." }
     
     \new voice \music   
     \shiftDurations #1 #0 {\music}
        >>
      }
\layout {
     \context {
       \Voice
       \remove Note_heads_engraver
       \remove Rest_engraver
       \consists Completion_heads_engraver
       \consists Completion_rest_engraver
       
     }
   }
