[OS X TeX] ``\mathit allowed only in math mode'' error while writing .idx

[Murray Eisenberg]

For a while I thought I had traced the source of the error to what _was_ an unmatched “$” in:

\renewcommand{\indexname}{Index}
\renewcommand{\preindexhook}{%
\emph{%
For $d\text{\emph{-ball}}$,  $d\text{\emph{-bounded set}}$, $d\text{\emph{-open set}}$, $(d,\,d')\text{\emph{-continuous map}}$, etc., see the corresponding entry \emph{ball, bounded set, open set, continuous map,} etc.%
\vskip\onelineskip}%
}
\printindex

Alas, commenting that out still gives an error when writing the .idx, but now on an index SUBitem (new log file attached).

Here’s my complete .ist, to which the error is conceivably related.

% MakeIndex style file
% output main entry <entry> as: \item \idxmark{<entry>}, 
item_0  "\n\\item \\idxmark{"
delim_0 "}, "
% not forgetting the subitem case
item_x1 "} \n \\subitem "
headings_flag 1
heading_prefix "{\\medskip\\hfill\\large\\textsf{\\textbf{"
heading_suffix "}}\\hfill}\\medskip\\nopagebreak\n”

Recall from my original messge that \idxmark is defined by:

\newcommand{\idxmark}[1]{{\let\gobbleone\relax\markboth{\sffamily\bfseries#1}{\sffamily\bfseries#1}}#1}
\providecommand\gobbleone[1]{}

I did manually go through the entire ..ind file to see if I could find an unmatched “$” in entries there, but I did not. Can any wizard with regex knowledge check that, too? So I’ve also attached the .ind file.
