dh_installtex just for calling mktexlsr? (was: Bug#358695: ITP: latex-utils -- utilities for LaTeX/xfig)

Hm, I think that it's good to have those checks, but only if they are
needed.  They are not needed if you depend on "tetex-bin |
texlive-base-bin", since in this case it's guaranteed that mktexlsr
actually works (libkpathsea is configured etc.).  But there may be
packages which install TeX input files, but do not depend on a TeX
system (instead only Recommend or Suggest).

I'm not familiar with dh_installtex code - would it be easy to add an
option, so that only the mktexlsr call is introduced into maintainer
scripts?  Should we provide an option to add directories to the mktexlsr
call, so that only the directories where files have been installed are
updated?  This could speed up things considerably, and there's no need
to update the font cache or TEXMFSITE, or a possibly large TEXMFLOCAL
when installing a couple of files in TEXMFMAIN.
