Hi all, I implemented a new face attribute "underwave". It does exactly what this thread[1] asked for. It only works on X11 currently. I've basically followed whatever "overline" was doing across all the source tree so it should be ok. I don't have a windows/mac machine to port this feature but it should be easy to do: just port the changes made to xterm.c to other *term.c. I've attached the diff and a screenshot of the splash screen with the default and link face changed to use underwaving. Note that it looks good on both X11 core fonts and Xft fonts. I would love to see this merged in emacs so -- if everything is alright -- what's the next step? PS: if you receive this message twice you can ignore the other one, sorry. 1: http://thread.gmane.org/gmane.emacs.devel/147873/focus=147905
