While it worked for some *predefined* refs, such as secret and even
subsecref, for automatically generated custom refs, the brackets
method for dealing with whitespaces doesn't work:
\label{sec:A B}
\secref{{A B}} -- works!
\label{sss:A B}
\sssref{{A B}} -- doesn't work:
LaTeX Warning: Reference `sss:{A B}' on page 1 undefined on input
I notice that LyX adds these lines to the tex file:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
\AtBeginDocument{\providecommand\secref[1]{\ref{sec:#1}}}
\AtBeginDocument{\providecommand\sssref[1]{\ref{sss:#1}}}
I think secref has been already pre-defined by refstyle, but sssref
wasn't, hence the above definition is used and leads to the error.
