My recent changes to add the ctl_renametf routine assumed that print job

control-files will always start with 'cfA*'.  It turns out that some
implementations of lpd (such as solaris) may send a control file which
starts with 'cfB*', or really 'cf<anyLetter>*'.  Although such filenames
are very odd, we did used to accept them.  This changes ctl_renametf to
work correctly with them, and fixes up 'lpc clean' to match.
