\begin {problem}
	I mostly open and close LaTeX-environments with blanks or tabs
	between the \begin or \end and the environment identifier,
	just like here.  The function TeX-close-LaTeX-block (on ^C^F)
	requires \begin{, without any whitespace.
\end {problem}

\begin {cure}
	Change the regexp in TeX-close-LaTeX-block to include any
	leading white space and the braces.  (The insertion of the
	corresponding closing line comes down to a simple
	(insert "\\end" text), because the match includes also the
	braces.)
\end {cure}
