Some further experiments (a small test program) revealed that the
termcap library produces the expanded entry for "ansi", but truncated to
1024 characters. Unfortunately, pretty important strings like cm (cursor
motion) are lost this way. I still consider this to be a bug.

And there are strange entries like ..sa= and ..rp=.

Problems also remain of course for programs that parse the termcap file
by themselves.
