"""Combine similar index entries into an entry and subentries.
|
|
|
|
For example:
|
|
|
|
\item {foobar} (in module flotz), 23
|
|
\item {foobar} (in module whackit), 4323
|
|
|
|
becomes
|
|
|
|
\item {foobar}
|
|
\subitem in module flotz, 23
|
|
\subitem in module whackit, 4323
|
|
|
|
Note that an item which matches the format of a collapsable item but which
|
|
isn't part of a group of similar items is not modified.
