[l2h] Broken enumerations

[Graham Gough]

Sorry Ross, but I'm afraid you're wrong this time (a rare event
indeed!). The command \usecounter sets the value of the counter back
to 0 again, so your suggestion won't work. See latex.ltx

   \def\usecounter#1{\@nmbrlisttrue\def\@listctr{#1}\setcounter{#1}\z@}

Mark Wooding has macros \suspend and \resume to tackle this problem in
his mdwlists package, I was just using a naive approach but some
mechanism is necessary to remember the value from one list to the
next. 

Best wishes

Graham
