New issue 1785 by address@hidden: Compressible space before the first  
note of a line ?
http://code.google.com/p/lilypond/issues/detail?id=1785

Things like Clefs and KeySignatures have a list of parameters (space-alist)  
specifying the space there should be to the following item.  Many of these  
specifications request 'fixed' space before the first note on each line.

The code and comments make it clear that 'fixed' space is not meant to be  
compressible, but since a seemingly accidental change four years ago, it  
has been.

Patch at <http://codereview.appspot.com/4188051/> posted with the one for  
issue 1779 since they affect the same code, but the fixes are separable --  
we can commit patches for either this or 1779 or both.

I could find no discussion of this point, so am inclined to restore the  
intent of the code.  No regression test breaks, some look tidier,  
especially the medieval stuff.  Any comments ?
