Compile warnings in new post/pslatex terminal code

[Ethan M. <merritt@u.washington.edu>]

Current CVS gives the following errors when compiled:
../term/pslatex.trm:260: warning: unused variable `tmp'
../term/pslatex.trm:150: warning: enumeration value `PSTERM_POSTSCRIPT' not handled in switch
../term/pslatex.trm:257: warning: enumeration value `PSTERM_EPSLATEX' not handled in switch
../term/pslatex.trm:257: warning: enumeration value `PSTERM_POSTSCRIPT' not handled in switch
../term/post.trm:2202: warning: enumeration value `PSTERM_POSTSCRIPT' not handled in switch
../term/post.trm:2309: warning: 'xmin_t' might be used uninitialized in this function
../term/post.trm:2309: warning: 'ymin_t' might be used uninitialized in this function
../term/post.trm:2309: warning: 'xmax_t' might be used uninitialized in this function
../term/post.trm:2309: warning: 'ymax_t' might be used uninitialized in this function

so far relatively trivial, though they ought to be fixed.
but then I get:

../term/post.trm:1463: warning: implicit declaration of function `conv_text'
../term/post.trm:1463: warning: format argument is not a pointer (arg 3)

This is bad.  Individual drivers should not be calling
back into the gnuplot core routines (conv_text is in show.c).
Is this conversion really necessary?  
Why do we care if a user manages to type in non-printing characters
in an epslatex header string?  "If it hurts, don't do it".
