Merge pull request 'Highlight braced stored-proc names in lappend arguments' (#42) from #41 into main

Treat braced lappend arguments that match custom or standard procedure names as
function tokens for semantic highlighting. This applies the same visual
highlighting as calls but does not treat the literal as executable Tcl. Previously
such braced stored-proc names were not highlighted.
