mapfile still appears to be behaving strangely on HPUX, sorry.


Sven: 6318: memory fixes for parameter module (and compctl).

Sven: 6322: reverse indexing of nested arrays

Sven: 6326: compadd -r and -R work on automatically added suffixes, too

pws: 6330: rewrite configuration system to use AC_SUBST_FILE instead
of including files by ed trickery (ed is now no longer required).

pws: 6331: protect against null hash tables in parameter module

pws: 6332: mapfile module

pws: 6335: now you can do ${(f)"$(...)"} to get arrays

pws: 6340: INSTALL didn't work if it was install-sh after 6330

Sven: 6343: test length of anchor in partial word matching

pws: 6345: Config/defs.mk is now in build tree, not source tree

pws: 6346: msync() missing from mapfile.c, somehow

Sven: 6352, 6354: more quoting in completion

Sven: 6355: ALL_EXPORT crashed the shell if set on command line

Bart: 6368: don't use cp -f, use rm -f in configure.in

Bart: 6369: fix use of relative paths in compinstall

Sven: 6374: autoremove behaviour on -r and -R, documentation

Sven: 6388: completion in braces removes later arguments

Peter seems to have completely forgotten to mention that a new scheme for
/etc/z* files is in pws-20 ... but it doesn't appear to be the scheme that
he said (in 6380) that he was going to implement.  It's "alternative #2"
with the GLOBAL_RCS option replacing GLOBAL_RCS_FIRST.

Sorry, I was playing around looking at what to implement, and this was the
last attempt I did.  I then forgot it was still in the source when I came
back and produced pws-20, so this is a mistake.  Here's a patch against how
it appears in pws-20, putting it the way we decided; this will fail against
all previous versions.  Seems to me it's pretty hard to find the default
option settings in the manual, but I defied convention by mentioning them
here.

One subtlety I hadn't noticed:  unsetting rcs (or setting norcs) causes the
history file not to be saved.  This has always been the case, but it's
something else to think about if you start playing around with rcs in your
own initialisation files, so I noted it in the manual entry.
