Subject: [PATCH] Add indentation for \if...-\else-\fi statements
* latex.el (LaTeX-end-regexp): "\else" and "\fi" will now
subtract from indentation.
(LaTeX-indent-level-count): add a special case for "\else", since it
ends an indentation block and starts a new one at the same time. "\if"
will now add to indentation level, unless there's a "{" on the same
line.
Note that there's no "\\b", so:
\ifdefinded will add indentation
\ifwindows will add indentation
\ifstrequal{#4}{} will not add indentation
