[tex-live] Bug#433455: /usr/bin/pdftex: $TEXEDIT default doesn't cope with spaces in filenames

a Debian user has found that the compile-time default for TEXEDIT, the
command used when pressing `e' (for edit) when (pdf)tex presents an
error message in interactive mode, does not work with filenames which
contain spaces.  The fix is easy, `%s' must be enclosed in double
quotes, but where should it be applied?

Hm, it's at least mentioned in texk/web2c/libs/texmfmp.c, but I can't
find where it's set.  Can anyone help me?

Of course it works to set it in texmf.cnf, the following patch should
do.  It's against Debian's /etc/texmf/texmf.d/95NonPath.cnf, so for
texmf.cnf in TL the line numbers will be far off:

By the way, does variable expansion work in this case?  In other words,

TEXEDIT = ${EDITOR:-vi} +%d "%s"

work and respect the EDITOR environment variable?
