It has been done. Hooray! @techee: there's only one issue pending which is whether it is OK to leave the comments I put in `group_SYSVERILOG` or if I should remove those as well.
I also re-generated the ctags unit tests for Verilog and added two for SystemVerilog. While doing so, I noticed a couple of issues/bugs in ctags (I think), but those should be fixed in ctags. I left the points of failure marked in comments in the unit tests.
Other than this, the PR is ready to go.
