Hi all,

(for reference: original discussion:
https://github.com/rstudio/tinytex/issues/427)

in TeX Live we are using runscript.lua
https://tug.org/svn/texlive/trunk/Master/bin/windows/runscript.tlu?revision=68820&view=markup
to resolve scripts, typical examples are
        fmtutil -> fmtutil.pl
        updmap  -> updmap.pl
etc (not only for perl scripts!).

It seems that in some cases, the scripts fails to resolve scripts,
for example
        fmtutil-sys
will use Windows "short name" passed in, like "FMTUTI~1.EXE"

My question: Is there a way in luatex to convert these short names
to "proper" (= long) names?
