[perl #117901] [BUG] prefix: and prefix: cause LTM error in hyphenated sub names like not-foo()

[Christian Bartolomaeus via RT]

This works now:

$ perl6 -e 'sub not-foo { "2" }; say not-foo();'
2

$ perl6 -e 'sub so-what { say "nyan"; }; so-what;'
nyan

$ perl6 -e 'sub m-foo { say "nyan"; }; m-foo;'
nyan

I added three tests to S06-other/misc.t with commit 
https://github.com/perl6/roast/commit/c3d0fa4d70

I'm closing this ticket as 'resolved'.
