Please help me! I can't figure it out. When I define
--------------
\newenvironment{teq}{\begin{equation}}{\end{equation}}
\begin{teq}
x^2 + y^2 = c^2,
\end{teq}
To get the correct generalisation of the rule as
presented in the previous chapter, we must set
--------------
the line following this displayed equation is indented by a
space. In this specific case, the output of dvitty is
--------------
x2 +y2= c2; (1)
To get the correct generalisation of the rule as presented in the
previous chapter, we must set
--------------
This looks like a bug in \newenvironment, or is this a
feature of one of those wonderful LaTeX commands?

This behaviour is the same for every LaTeX environment, except for a few special ones (like equation) that explicitly discard spaces following their \end tag. [Classified information: this is done by setting a global switch to true, with the name of `@ignore'. The \end command checks that switch and calls TeX's \ignorespaces primitive, if necessary.] Rainer Sch\"opf
