This is from a last-minute addition to my fix to issue 1785.
The affected tests are those that have very few notes stretched a line.

The space after key- and time- signatures was formerly "fixed-space".
There was code that tried to make "fixed-space" be relatively  
incompressible, but it was not working as intended since about version  
2.10.24-ish.  "Fixed-space" was unstretchable, but it would compress  
easily.  That was issue 1785.

While reviewing the fix to issue 1785 Janek noted that strictly  
incompressible space after key signatures looked bad on tight scores.
There is a choice "semi-fixed-space" in the framework for space after  
prefatory matter.  Such space stretches as well as it compresses.  Checking  
code comments and textbooks and mailing archives, I found no reason for  
LilyPond to have inflexible space after time- and key-signatures, so I  
changed it to "semi-fixed-space"

Do we want the space after key- and time-signatures to be non-stretchable ?

If so, just revert cc88cd3680 .

If nobody has any reason to want the space to be inflexible, I'll mark this  
invalid after a week or so.
