Registering to an operator with R=xxxxx in libgsmd-tool -m shell
results in
R=12345
# Unknown command `R=12345'
. This has been broken since revision 3657, 2007-12-17.
When fixing it I cleaned up the handling of all commands taking
arguments, which also fixes the segfaults when too few arguments are
given to most commands (try typing e.g. just "pr") and a problem when
a command works even when there is trailing garbage in the command
name (e.g. "prxxxxxxxxx=1").
