In commands which accept a `msgs' argument, the default is either
\*(lqcur\*(rq or \*(lqall\*(rq, depending on which makes more sense
for each command (see the individual man pages for details). Repeated

the selection from being a range of up to `n' messages, to being a
selection of just the `n'th message. So while \*(lqseq:5\*(rq

when reading and writing sequence files. The locking mechanisms supported
