[tex-k] Broken "-tex" option in MetaPost

[Igor Liferenko]

Hi,

MetaPost, version 2.00 (TeX Live 2019/dev/Debian) (kpathsea version 6.3.1/dev)

When I run

    rm -f test.mpx test.eps; /usr/bin/mpost test

and

    rm -f test.mpx test.eps; /usr/bin/mpost -tex=tex test

on the following file:

outputtemplate:="%j.eps"; prologues:=3;
beginfig(1);
label.lrt(btex \font\x=cmcyr10 \x priwet etex, (0,0));
endfig;
end

I get different outputs: in the second case bounding box for figure
is smaller, which causes part of the word to be "cut-off" in previewer.

This is the diff of correct and incorrect output:

(the case "-tex=tex" was found to be minimal thing that reproduces the bug,
actually I'm using another executable to use my own format)
