LaTeX pkg changes: @ in .loc file

The .loc file used to generate the list of changes breaks if it contains macros with '@' in their name, in my case \slimits@. I then got the error that \slimits was not defined.

I fixed it in my document by adding

\AtBeginDocument{\addtocontents{loc}{\protect\makeatletter}}
\AtEndDocument{\addtocontents{loc}{\protect\makeatother}}

to the preamble.
