That was caused by a bad 'stty' setting, as you guessed, since fixed.

Bill Poser and I looked at the source code, and it appears it wouldn't 
be too hard to plug in a call to the readline library (libreadline) in a 
loop, so that the loop exits when the user types a line consisting of 
just a period.

I have the choice, but my fingers know rcs :-).  I use it both on Linux 
and Windows (the latter using the very nice CS-RCS front end).  Also, 
some of these other systems apparently don't play well with Windows (the 
wikipedia article on 'git' lists that as a drawback).

If I did go with another version control system, I'm not sure which one 
it would be.  I presume cvs is still a contender, and offers advantages 
over RCS when multiple users want to modify the same file (although I 
haven't wrapped my mind around how that works--most of my work up until 
this point has been single-user modifications, namely my own).

Another criterion I would have for a replacement version control system 
is that it treat XML well.  I'm not sure what I mean by that, since XML 
files are in "just" plain text files; but diffing XML files with the 
traditional diff program often seems unenlightening.  I believe there 
are XML diff programs that do a better job, although I suppose that's 
not a topic for this group.

I might try that.  Alternatively, if Bill and I were able to modify rcs 
so it used the readline library, would it be of general enough interest 
to get into a new version of rcs?
