tweaks to reduce (not yet fix) Fatal errors being counted multiple times
->closeToNode takes optional arg to avoid errors if node not open
strip out undefs before building List
UnTeX now adds { and } to (try to) make the string valid TeX
Don't form redundant List for body
insertBlock is more careful about closing; \par disappears in preamble (it does it itself, rather than require special code in Stomach); careful about reversion of \over
remove debugging message
avoid undefs if secondary markup fails; don't put stretchy on mtext
avoid undefs if secondary markup fails
avoid undefs if secondary markup fails
Fatal if cwd fails (generally some OS or locale problem?)
Read the optional arg to \rotatebox, for origin -- we'll still have to implement the origin
add proper reversions; avoid Number|Dimension args to Macros (inefficient); avoid creating redundant <g>
more complex invokeToken to avoid several layers of stack; avoid creating unnecessary List
