Thibaut Cuvelier 4412fdf09a MathML test case: fix a typo.
It was bugging me when looking at XHTML output: I was wondering if LyX was doing anything weird about ligatures! Hopefully not.

Macro Testcases
\end_layout
\begin_layout Enumerate
Simple macro definitions with position awareness:
\begin_inset FormulaMacro
\newcommand{\bla}{42}
\end_inset
\begin_inset Formula
\[
\bla\mbox{ should look like }42
\]
\end_inset
now redefined as
\begin_inset FormulaMacro
\renewcommand{\bla}{21}
\end_inset
,
such that
\begin_inset Formula
\[
\bla\mbox{ should look like }21.
\]
\end_inset
\end_layout
\begin_layout Enumerate
Redefinitions of macros appearing in the definition of another macro:
\begin_inset FormulaMacro
\newcommand{\fooa}{x}
\end_inset
\begin_inset FormulaMacro
\newcommand{\foob}[1]{(#1\fooa)}
\end_inset
\begin_inset FormulaMacro
\renewcommand{\fooa}{y}
\end_inset
with the \SpecialChar TeX
code
\begin_inset listings
inline false
status open
\begin_layout Plain Layout
\backslash
newcommand{
\backslash
fooa}{x}
\end_layout
\begin_layout Plain Layout
\backslash
newcommand{
\backslash
foob}[1]{(#1
\backslash
fooa)}
\end_layout
\begin_layout Plain Layout
\backslash
renewcommand{
\backslash
fooa}{y}
\end_layout
\end_inset
gives the following:
\begin_inset Formula
\[
\foob{\fooa}\mbox{ should look like }(yy)
\]
\end_inset
\end_layout
\begin_layout Enumerate
Arity change:
\begin_inset FormulaMacro
\newcommand{\foo}{-}
\end_inset
\begin_inset FormulaMacro
\renewcommand{\foo}[2]{(#1,#2)}
\end_inset
\begin_inset Formula
\[
\foo{abc}d\mbox{ should look like }(abc,d)\mbox{ if the second foo is there, otherwise like }-{abc}d
\]
\end_inset
\end_layout
\begin_layout Enumerate
Arity change with incomplete arguments at line end:
\begin_inset FormulaMacro
\renewcommand{\foo}{-}
\end_inset
\begin_inset FormulaMacro
\renewcommand{\foo}[2]{(#1,#2)}
\end_inset
\begin_inset Formula
\[
\frac{\foo{abc}{}}{1}\mbox{ should be }\frac{(abc,\,)}{1}\mbox{ if the second foo is defined. Otherwise }\frac{-{abc}{}}{1}
\]
\end_inset
\end_layout
\begin_layout Enumerate
Recursion:
\begin_inset FormulaMacro
\renewcommand{\foo}[1]{\foo{#1}{}}
\end_inset
.
The inner foo should not we resolved as \SpecialChar TeX
would give a infinite recursion.
\end_layout
\begin_layout Enumerate
Recursive usage:
\begin_inset FormulaMacro
\renewcommand{\foo}[3]{\frac{{\displaystyle #1}\,{\displaystyle #2}}{{\displaystyle #3}}}
\end_inset
can be used to create tree-like structures like this one:
\begin_inset Formula
\[
\foo{\foo{42}{\foo{asdf}{asdf}{asdf}}{21}}{\foo{asdf}{asdf}{asdf}}{asdf}.
\]
\end_inset
\end_layout
\begin_layout Enumerate
Folding/Unfolding:
\begin_inset FormulaMacro
\renewcommand{\foo}[2]{<#1|#2>}
\end_inset
.
Start using Ctrl-+ and Ctrl when you are inside of the macro to fold and unfold,
e.g.
here:
\begin_inset Formula
\[
\foo{\foo{42}{12}}{\foo{21}4}.
\]
\end_inset
\end_layout
\begin_layout Enumerate
Scripts:
\begin_inset FormulaMacro
\renewcommand{\foo}[3][A][B]{(#1,#2)#3}
\end_inset
\begin_inset Formula
\[
\foo[a]{}^{4}[b]c_{1}\mbox{ should look like }(a,B)\sqcup^{4}[b]c_{1}
\]
\end_inset
\begin_inset Formula
\[
\foo[a]c^{3}\mbox{ should look like }(a,B)c^{3}
\]
\end_inset
\end_layout
\begin_layout Enumerate
Multiple optional parameters:
\begin_inset FormulaMacro
\renewcommand{\foo}[3][a][b][c]{(#1,#2,#3)}
\end_inset
\begin_inset Separator latexpar

\begin_layout Enumerate
\begin_inset Formula $\foo[][B]123\mbox{ should be }(a,B,c)123$
\end_inset

\begin_inset Formula $\foo[][][C]123\mbox{ should be }(a,b,C)123$
