more reformatting - label placement

Indent all labels one space.  Having uniform placement makes spotting
them much easier.  (Having no indent at all would impact the change
bars of 'git diff'.  Those display the last unindented line--which
doesn't start with punctuation--occuring before each band of changes,
so usually the name of the function being changed now that we no
longer have unindented K&R-style function argument declarations.)

While in there, shorten or split various wide lines and replace a few
tabs with spaces.
