When I compile a file using Emacs AucTeX with
C-c C-c (which runs
TeX-command-master which runs
TeX-run-TeX) the top line of the log output looks like this:
Running `LaTeX' on `mwe' with ``pdflatex -interaction=nonstopmode "\input" mwe.tex''
(This is the top line of the buffer when I do
Why on earth is aucTeX doing
"\input" mwe.tex rather than just
mwe.tex? What can this possibly achieve apart from causing my
%&custom fmt definition to get ignored?
And secondly, where do I stop it doing this? I've looked at how the various commands mentioned above are defined. None of them seem to specify this behaviour. So what is actually causing this invocation of pdflatex?
