"Wrapping" ligatures in spaces
I'm starting to "wrap" ligatures in spaces to avoid current problems like this:

Some ligatures can only have space to one side though and maybe some ligatures can't have spaces at all?
e.g. < ! - - won't work but< ! - - will
If you can see other examples like this amongst current ligatures then please let me know :)
other examples include mm ligature that can have no spaces and end html comment that can only have a leading space - - >
Was just thinking we should throw together a ligature test page that has various code snippets where the ligatures would be used. We could quickly load that in different editors to see how it looks.
@mikebronner would be cool - difficult to cover "everything" so I think doing some more conservative ligatures (i.e. wrapped in spaces) is a good approach. Then if people want the ligatures to work without spaces we can also "loosen up".
What I'm currently doing is using http://symbolhound.com and searching for the ligatures in the font I've yet to use myself to see what context they're used in to see if they can be wrapped in spaces
