Localized English words ('See', 'see', 'Short Table of Contents') (TeX output)

Hi all.

Operating System: Linux From Scratch (LFS) 12.4 - System V Edition
texi2any (GNU texinfo) 7.2

I just finished translating the manual for GNU Texinfo into Brazilian
Portuguese.

However, I need to change some words in the output (I generated the
HTML version, only for inspections).

I found a thread that (almost) discusses the same subject:
https://lists.gnu.org/archive/html/help-texinfo/2025-12/msg00001.html

Different from that, I made some tests. I have a 'texinfo.tex' file in
my operating system at '/usr/share/texmf/tex/texinfo/texinfo.tex'.

In my 'texinfo.pt_BR.texi', in the first line, I just deleted the
'\input texinfo.tex    @c -*-texinfo-*-' line.

I did expect an error from texi2any (texi2any --html --no-split
--output=3Dteste-mono.html texinfo.pt_BR.texi).

However, surprisingly, 'teste-mono.html' was output!

That made me think '/usr/share/texmf/tex/texinfo/texinfo.tex' was not
used. So, which 'texinfo.tex' was used?

Same about 'txi-pt.tex' (/usr/share/texmf/tex/texinfo/txi-pt.tex). I
need some different words from that file ('txi-pt.tex') and I can not
get it. What am I missing?

Please, in the response, tell me what commands to issue. :)

Thank you in advance.
