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. --- Doc/Zsh/files.yo.rcs2 Tue Jun 1 09:20:31 1999 +++ Doc/Zsh/files.yo Tue Jun 1 09:24:21 1999 @@ -8,13 +8,12 @@ pindex(NO_RCS, use of) pindex(NO_GLOBAL_RCS, use of) Commands are first read from tt(/etc/zshenv); this cannot be overridden. -If the tt(RCS) option is unset, no further files are read; changing this -option after this point has no effect on initialization files, but may -affect behaviour on logout.
