The \injlim command should generate only a single <mi>

[fred-wang]

The following commands generate an <mi> for each letter of the text, instead of a single <mi>, which is semantically better.

\injlim
\projlim
\varinjlim
\varliminf
\varlimsup
\varprojlim

The test pages are:
LaTeXToMathML/limits-2.html
LaTeXToMathML/limits-2-ref.html

This gives incorrect spacing in Firefox:
https://bugzilla.mozilla.org/show_bug.cgi?id=320294 (fixed in Firefox 13)

Also, MathPlayer reads it "I N J L I M". The reference is read a bit better, although not entirely correct: "In J Limit" .

The issue215 branch of my fork of MathJax should resolve this.

OK, I verified the fixed on Chrome, Opera and Firefox and updated the test.

=> Ready for release
