I have made the equivalent of this request to Apple, but
apparently the NetBSD libedit library is the primary source.

Could you please add the equivalent of the function
remove_history() to libedit, with a prototype in readline.h or
history.h as appropriate?  The function add_history() is already
present, so it seems logical to implement remove_history() as
well.  Both are present in recent versions of GNU readline.

Inspection of the GNU source for the readline library shows
remove_history() to be pretty simple, maybe simple enough that
its expression is inevitable, so maybe nothing special has to be
done to avoid contamination by the GPL.  But I am not a lawyer.

The immediate occasion for this request is an attempt to build
the very nice open source plotting package asymptote-0.82 in Mac
OS X (Tiger).  It uses remove_history(), and builds fine when
the reference to it is removed, at the expense of a little
crippling of functionality.
