That works as long as we are sure that a variable contains only paths.
It does not generally work with stuff like 

$ grep TEXDOC src/Upstream-source/TeXLive/Build/source/texk/kpathsea/texmf.in
TEXDOCSSUFFIX   = ;.pdf;.ps;.dvi;.html;.txt;.tex
TEXDOCSCOMPRESS = ;.gz;.bz2;.zip;.Z

(it does in this particular case, because the `.' separator is included,
and because `Z' comes last, but that's a lucky coincidence).  So either
we decide now to not allow non-path information in kpathsea list
variables, or we shouldn't be too bold with introducing "clever"
