Which is indeed a problem of a 'bare' line end. My mail might have been
missleading, sorry. The problem is not, that you have a real blank (' ')
before the line end. TeX (and therefore also musixTeX) interprets *the
line end character itself* as a blank character, if it doesn't directly
follow a control sequence like \en or \bar. So each line has to end either
with a command sequence or with a comment character ('%') in order to
make the line end character invisible to musixTeX.
\def\atnextbar{...}%
