label whitespaces no more

[Igor]

Thank you, Daniel: indeed even a simple
\newref{sss}{}
in the LaTeX preamble for my .lyx document solves the problem by
replacing the automatically LyX-generated definition:
\AtBeginDocument{\providecommand\sssref[1]{\ref{sss:#1}}}

Your command \sssref{} is just a standard latex definition. In refstyle the argument is processed further. Please read the documentation- refstyle.pdf, refconfig.pdf. This is where the original problem with spaces in labels originates. The algorithm removes all unbracked spaces to parse a comma separated list.

The second point is that in standard latex, spaces in labels is a newish thing. It was not always there. Also note even if you put 10 spaces in a row in a label, latex only passes one through to the definition - see the .aux file. I think it is better to use an underscore _ or include your label in brackets {aaa}.
