Hi Herb,

\textit does apply italic correction as this example shows

\documentclass{article}

\begin{document}
\textit{f}g

fg
\showoutput
\end{document}


gives

....\hbox(0.0+0.0)x15.0
....\OT1/cmr/m/it/10 f
....\kern 2.11945
....\OT1/cmr/m/n/10 g
....\penalty 10000

Actually

\DeclareTextFontCommand{\textit}{\itshape}

and

\DeclareTextFontCommand{\emph}{\em}

(similarly for the others)

and

\DeclareTextFontCommand:
macro:#1#2->\DeclareRobustCommand #1[1]{\ifmmode \nfss at text {#2##1}\else \hmode at bgroup \text at command {##1}#2\check at icl ##1\check at icr \expandafter \egroup \fi }

has \check at icl, \check at icr related to italic correction at start and end

and at some point they will involve this, where I keep only code comments

\def \maybe at ic {\futurelet\@let at token\maybe at ic@}
\def \maybe at ic@ {%
We fi
rst check to see if the current font is positively sloped. (But do not forget
the message Rainer sent about an upright font with non-zero slope! Or is this an
urban myth?) It has been suggested that this should test against a small positive
value, but what?
... code lines ...
}


Best,

Jean-François
