[texhax] Preserve space at end of expression enclosed in braces

[Dan Hatton]

Dear All,

I've defined commands as follows:

\definecolor{LBRed}{rgb}{0.9,0.1,0.2}
\definecolor{LBBlue}{rgb}{0.4,0.3,1.0}

\newcommand{\morerefadd}[1]{{\color{LBBlue}#1}}
\newcommand{\morerefchange}[2]{{\color{LBRed}#1}{\color{LBBlue}#2}}
\newcommand{\morerefdel}[1]{{\color{LBRed}#1}}

to do revision tracking and highlighting on a document.

Now, I want to put a space between two words (because words should
have spaces between!) with something like

\morerefadd{ }

but the space doesn't appear in the output of LaTeX.  In fact, even
when I put

\morerefadd{ some other text}

the initial space doesn't appear.  Any ideas please?

Dan
