Turn off auto-insertion of italic correction (undesired extra kerning)

The LaTeX2e font selection manual states

Commands defined by \DeclareTextFontCommand automatically take care of any necessary italic correction (on either side).

So running the following example

\documentclass{article}\begin{document}\showboxbreadth=\maxdimen\showboxdepth=\maxdimenf\textbf{H}f\showlistsf{\bfseries H}f\showlists\end{document}

will produce the following relevant log

% for f\textbf{H}f\OT1/cmr/m/n/10 f\kern 0.77779\OT1/cmr/bx/n/10 H\kern 0.0\OT1/cmr/m/n/10 f% for f{\bfseries H}f\OT1/cmr/m/n/10 f\OT1/cmr/bx/n/10 H\OT1/cmr/m/n/10 f

In certain applications, however, it is desired not to automatically insert the italic correction at all. How can I selectively/locally turn off the auto-insertion of italic correction from the \textXX{...} commands?
