The following changes enhance the way texvc handles space around
mathematical function names when translating to HTML; adds support for
the sen, the Spanish name for sin; and corrects a bug that eliminates
spacing around \operatorname{...} in the resulting png. More
specifically, texvc now dectect whether or not a
standard function such as is followed by a delimitier such as (, {, [
etc. and adds a space or not as appropriate. This issue The code has been
reorganized to include a list of standard LaTeX commands whose spacing
rules are the same, and treates them all on an equal footing. It
similarly treats functions defined for mediawiki in the same way it
treats standard latex functions. One addition function is added, \sen,
and others can be added easily if necessary. Finally LaTeX generated
by texvc contained to many braces which altered the spacing created by
the command \operatorname, this has now been corrected. These last
two changes address the issues raised in bug 18912 and the chaning in
translation to HTML address most, but not all, of the issues raised in
bug 6722 .

Revision r87117 corrects a small bug introduced in this change. which results to not inserting a space after the function name when no braces are used. That is if the input was the the code sent to LaTeX was \sinx.

This looks like a good refactoring of many \foo commands into a smaller set of code. I'm surprised about extra { } in latex producing misrendering, but guess it's possible.

Needs parser tests to confirm the change and prevent regressions.

Provisionally reverted in r96990 pending test cases.

This seems to stop things in the pattern \sin{x} from working; I see \sin{...}, \cos{...}, and \tan{...} in 583 equations on, such as on w:en:Anomalous Diffraction Theory

Reapplied in r97034 along with test cases & some friends; a couple more revs that hadn't been obviously connected resolve this issue.
