[PATCH] bug in showing/setting remake options

[R. Bernstein]

I just discovered a bug in rc2 in trying to show/set remake options.
(Also athere was small bug in remake, but that's been fixed in the git
source now.)

Attached is a proposed patch which contains 3 hunks. 

The first hunk tells ddd that multi-line remake's "set xx" output
doesn't show subcommands like it does in gdb.

The second hunk silences a gcc warning about operator precedence more
explicit. Not strictly needed.

The final changes are sort of a defensive measure against the kind of
looping that just occurred - a limit (75) is put on the maximum number
of button settings.

Andrew: if you want me to apply direcly to SVN let me know. Or
modify/amend as appropriate.
