Correct a host of small formatting issues with Texinfo manual (bug #52774) basics.txi: Move all of the Octave command line option references that begin with a hyphen to underneath the concept-index entry "options, Octave command" using the @sortas command, leaving some indentation space with @ @ . Add a missing @cindex reference for the --eval option and the -W option. Remove the deprecated -? help option. Move the ~/.octaverc and .octaverc index entries to "octaverc" via @sortas. Add an index entry for startup.m. Move the ~/.inputrc index entry to "inputrc" via @sortas. Move the #! index entry from concept index to operator index, qualifying with "self-contained script". Move the #, %, #{ and %{ index entries to the operator index qualifying with "comment marker" or "block comment marker" accordingly. expr.tex: Move the ":end" index entry to "end" via the @sortas command and include "end:" as well. stmt.txi: Change ... and \ index references from @cindex to @opindex and position near paragraph reference. xticks.m: Fix a set of three bogus index entries by supplying a missing field with {} for examples in which the function does not return output. xticklabels.m: Ditto. yticks.m: Ditto. yticklabels.m: Ditto. zticks.m: Ditto. zticklabels.m: Ditto. rticks.m: Ditto. thetaticks.m: Ditto.
