This is a bug in fontdoc.sty; it turns out \IfFileExists is more fragile
than I though it was, and this causes problems when \inputetx gets nested.

Replacing the definition of \inputetx in fontdoc.sty with the following
code fixes the bug:

\def\inputetx#1{%
   \begingroup
      \edef\lowercase at file{\lowercase{%
         \edef\noexpand\lowercase at file{#1}%
      }}%
      \lowercase at file
      \global\slot at number=0%
      \FD at slot@known at true
      \IfFileExists{\lowercase at file.etx}{%
         \FD at relax@encoding at tricks
         \@@input \@filef at und
         \let\relax=\x at relax
      }{%
         \PackageError{fontdoc}{File #1.etx not found}%
            {\@eha\MessageBreak You can \protect\inputetx\space
             some other file now, if you want.}%
      }
   \endgroup
}
\def\FD at relax@encoding at tricks{%
   \def\relax{\let\relax=\x at relax\iffalse}%
   \let\encoding=\fi
   \outer\x at cs\def{endencoding}{\endinput}%
}

No, that is probably just out of sheer forgetfulness.
