Special treatment for some commands - e.g. \index

[pauloney]

The command \index shows up in TeX with a variable number of arguments, depending in particular, on the package one is using to handle multiple-indexes.

The following input:

one\index{two}{three}

is parsed yielding (on the older version of detex)

one twothree

and yielding (on the new version):

onetwo three

while the correct should be:

 one two three

or even arguably only

 one three

since "two" which is the name of the Index here is not all that interesting for spellers.

Even in the case where there is a NEWLINE after the \index{} entry, detex (the new one) is not respecting it and joining the words before and after:

\documentclass{report}

\begin{document}

An atlas of\index{Atlas}
dimension ...

\end{document}

that becomes:

An atlas ofdimension ...
