With the current git master (commit 4530b19e606c56410), there is no change
to the output. The '\texorpdfstring ...' output is still used. It appears
from the code that this would always be used inside the argument to @part.
} elsif ($self->{'formatting_context'}->[-1]
->{'in_sectioning_command_heading'}) {
# add command to substitute a space in table of contents
# if in heading command.
$result .= "\\texorpdfstring{\\leavevmode{}\\\\}{ }";
} else {
# In internal horizontal or vertical mode, convert explicit line
# breaks from @* into spaces for page heading lines. The
# code is based on Texinfo TeX code, but with a different
# code for the case where an end of line is output.
# NOTE \leavevmode{} is added to avoid
# ! LaTeX Error: There's no line here to end.
$result .= "\\ifinner\\unskip\\space\\ignorespaces".
"\\else\\leavevmode{}\\\\\\fi%\n";
}
