tex2lyx is no longer compilable

[Uwe Stöhr]

Hi Georg,

thanks for your code optimizations. But as I wrote in the commit message
http://www.lyx.org/trac/changeset/e7c75296d6f13e1bb08b254f3a2fe3c57ccf6bae/lyxgit
we were at the nesting limit for if clauses allowed by MSVC. Now we have too many nested if and 
therefore I get:

  ..\..\..\src\tex2lyx\text.cpp(4599): fatal error C1061: compiler limit : blocks nested too deeply 
[D:\LyXGit\Master\compile-result\src\tex2lyx\tex2lyx.vcxproj]

regards Uwe
