It fixes the bug by returning an empty string if the math tag is
empty.
Parser tests and changes so that white-text only works.

Previous parser tests assumed the older options which turned some simple bits into HTML, while new default runs everything through images.

but \operatorname to fix Bug 31442. More specifically, TEX_FUN1 now
adds braces as it did in previous versions. The result is texvc will
once again correctly sanitize multiple math accents even when no braces are
given (e.g. \dot \vec B) and it will allow math accents to be used with
symbols whose font as been changed (e.g. \tilde \mathcal{M}). Parser
tests are created to ensure these continue to work.
The handling of \operatorname is now handled specially by the
function TEX_FUN1nb (nb stands for no braces and the name is taken to
be consistent with the existing function TEX_FUN2nb). The addition of
braces causes this command to LaTeX incorrectly. The parser test for
\operatorname has been updated to reflect the fact the hash of the
images involved has changed.
* (bug 18912) Add math support for \sen Spanish variant of \sin
* (bug 18912) Fix spacing for \operatorname in math
Reapplies r86962, r87117, r87936, r87941 plus some parser tests.
Note that further batch testing to identify any other potential problems due to the spacing tweaks is a good idea!
Reapplied r87092 (tests added, tweaked for merge, no functional diff) to allow "'" and "`" in \text{...} bits.
I'm not convinced this is a sufficient fix -- there are probably a *lot* more where this came from.
But it doesn't hurt to add them!
May require texlive-lang-greek package to be installed; but it's only loaded when these bits are used.
Reapplied r87298 plus parser test case to confirm the new chars can render and the existing \digamma hasn't changed.
Reapplied r87284 with a tweak to allow \euro through to conservative HTML output.
Parser test case added to confirm that \euro is HTMLable and the other euro variants are renderable to images.
This commit also includes tweaks to HTMLification of \phi, \varphi, and \varepsilon (conservative HTML) and changes the non-conservative HTMLification of number sets from plain letters to the dedicated Unicode chars for their symbols. These changes are not included in tests, but don't alter what input is supported.
Reapplied r86965 (patch by Thenub314), plus parser test case to ensure that \widetilde{x} actually renders. (While we can't compare the contents of the image, the output hash will remain stable in the img url. Forcing $wgMathPath to a fixed fake path for parsertests.
* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable
math conversion after upgrading, obtain the Math extension from SVN or from
http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php:
require_once "$IP/extensions/Math/Math.php";
This is an initial stab, and a few things remain to be cleaned up:
* messages need to be moved from core to extension
* MW_MATH_* constants should be moved to the extension from core
* old back-compat math names interfaces using those constants should be removed from message files
* classic edit toolbar's math button should be added from the extension (or else dropped) -- currently there's not a clean hook, but could do it by JS
* couple of things like the 'armourMath' function on Language & LanguageConverter may want to be redone just as an unconditional, if that's simpler.
Setting $wgUseTeX alone will no longer have any affect. The var's still there for the moment as a few bits still need to be fully moved out from core.
