Subject: Avoid a couple warnings reported by gcc.
X-Git-Tag: v1.1~6
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/f2f75f25ecc377fb95877449aa12314ee1385a1f

Avoid a couple warnings reported by gcc.

There would be a presentation bug in the "help" command output if
we had anything in the list sufficiently long to cause wrapping.
