2001-06-27 Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr>
* src/insets/insettabular.C (getMaxWidth): do the speedup in a
different way, remove dead code
* src/tabular.C (GetCellInset): store the last cell checked (gotten)
* src/tabular.h: new member cur_cell, used to cache cell values.
2001-06-24 The LyX Project <jug@sad.it>
* src/lyxlex_pimpl.C (compare_tags): use compare_ascii_no_case instead
