Re: What's remembered? "S" flag suggestion

[Derek R. Price]

Don't ask me!  The point of this was that I don't really have any
particularly strong opinions on this issue yet.  Convince some of the other
people out there and maybe I'll venture an opinion.  It's probably worth
noting that `cvs -qn up' seems to accomplish much the same thing as your
script (aside from the file counts), though I haven't actually tested the
script and my awk is a bit rusty.

I think I have been persuaded by the original argument in this thread that
"S" (or "T", but I'm not sure I like the overloading since for tag & rtag,
"T" can mean a branch or a static tag) is a useful status message from `cvs
update' when the user tries to update a file with a static tag.  Or perhaps
"S" for static tag and "s" for static tag but modified file or something,
but that has the potential of breaking scripts which were dependent on the
'M'.

Well, okay, I guess this deserves more discussion then.  Anyway, how about a
single warning for all files when the sticky static tag is discovered.  On
stderr probably.  It seems to me that this would provide the requested
functionality as well as preserving the old API, for the majority of cases
(bulk/recursive operations).  In the rare exceptions, the user could resort
to `cvs status' to trace the source of the problem if they wished...

Any comments?
