   Sure, I have several macros that I use this way.  But it is always
   annoying that I sometimes forget to put in the extra \ in the all
   places where I need a space.  Has somebody got a macro that will put
   in a space unless the next character is a punctuation mark?

I wrote a macro \AfterMacro, a couple of years ago, that I sometimes
use this in macro packages intended for people with NO TeX 
experience at all. Myself, I think it's better to use the \Tleid\
notation. You can use \AfterMacro in macro definitions, that expands to
abbreviations or names or formulas.

\def\AfterMacro#1{\if#1,,\else	% Feel free to add more punctuation
                  \if#1..\else  % marks, as you need them.
                  \if#1!!\else
                  \if#1??\else
                  \if#1::\else
                  \if#1;;\else
                  \if#1''\else
                  \if#1))\else
                  \if#1-\-\else % NOTE: '-' epands to '\-'
                  \ #1\fi\fi\fi\fi\fi\fi\fi\fi\fi}

\def\tEx{\TeX\expandafter\AfterMacro}
\def\jon{Jonathan\expandafter\AfterMacro}
\def\Tleid{\ifmmode T_{\rm Leid}\else$T_{\rm Leid}$\expandafter\AfterMacro\fi}


This is how to use \tEx in a sentence, which could also end with \tEx.
This is how to use \jon in a sentence, which could also end with \jon.
\jon's car (owned by \jon) is green. You can use \Tleid (Yes,
\Tleid!!) in the text or in a formula $\Tleid < 2\Tleid$.
