actually no.

For extensionless files .tex is looked for first  (so readme is not
accessible if readme.tex is blocking it)


% If this option is set to true, `tex a.b' will look first for a.b.tex
% (within each path element), and then for a.b, i.e., we try standard
% extensions first.  If this is false, we first look for a.b and then
% a.b.tex, i.e., we try the name as-is first.

% Both names are always tried; the difference is the order in which they
% are tried.  The setting applies to all searches, not just .tex.

% This setting only affects names being looked up which *already* have
% an extension.  A name without an extension (e.g., `tex story') will
% always have an extension added first.

% The default is true, because we already avoid adding the standard
% extension(s) in the usual cases.  E.g., babel.sty will only look for
% babel.sty, not babel.sty.tex, regardless of this setting.
