bug in fermata over multi-rest and in instrument-names

[Herman Grootaers]

Ladies/Gentlemen,

I am currently busy with writing a number of choral parts, in which I 
have used a lot of features of Lilypond.

I am currently using lilypond 2.7.34-1 and two bugs got my attention.

The placement of a fermata over a multi-measure-rest is wrong when you 
say that is must be under the staff. I mean that the fermata printed is 
as if it is above the staff instead of under the staff.

Further, in 2.7.33 the instrumentnames were not engraved, and are now 
back, but the layout is not correct.

I am using the attached script to generate the wrong output.

Can someone help me in resolving this.

Greetings,
Herman Grootaers
