[texhax] unexplained space

I'm not sure why, but your email got formatted terribly in my client
(Windogs Outlook); that's why I "snipped" it.

Anyway, a reasonable rule-of-thumb is to put a comment (%) at the end of
every line that would otherwise end with a right brace (}).  That is, write 

  \typeout{Hello Wordl}%

To be more explicit, a simple command with no parameters, such as \par,
\else, \centering etc. will always eat the following space while, say,
\typeout{Hello World} will not (ie, the space will remain as a physical
space in your output).  And the end-of-line character is always interpreted
as a space.

That said, there are, of course, always exceptions.

So, just add end-of-line comments until you're happy.

Cheers,  Phil
