[tex-k] kpsewhich exit status

[Reinhard Kotucha]

Hi,

$ kpsewhich --expand-var=\$TEXMFLOCAL; echo $?
/opt/tex/texlive/alpha/texmf-local
0
$ kpsewhich --expand-var=\$NONEXISTENTVAR; echo $?

0

If kpsewhich --expand-var is successful it provides the value of the
variable.  If not, it returns an empty string.

In both cases the exit status is 0.  It is certainly not important
what kpsewhich writes to stdout if a variable cannot be resolved, but
in this case the exit status should be $\ne 0$.  Or am I doing
something wrong?

Regards,
  Reinhard
