* history.c (history_do_write) Build a buffer of all of the lines
to write and write them in one fell swoop (lower overhead than
calling write () for each line). Suggested by Peter Ho.
* vi_mode.c (rl_vi_subst) Don't forget to end the undo group.
Sat Mar 7 00:15:36 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* Makefile.in: remove FIXME's on info and install-info targets.
