This cannot be fixed, because nano uses regexes for coloring things, and always applies all coloring rules to any line -- there is no mechanism to make a rule stop the processing of further rules.
So, '//' cannot prevent the recognition of '/*' on the same line. You yourself can edit the c.nanorc file and make this change: -color brightblue start="/\*" end="\*/" +color brightblue start="(^|\s)/\*" end="\*/" This will recognize '/*' only when it is at the start of a line OR preceded by whitespace. This prevents misinterpreting '//*' as a start of multiline comment. But this does not colorize an inline comment/*like this*/correctly, and I value this more than the '//*' case. So... won't fix. By the way, your example is not well aligned: > //***********************
// A nice extended comment //***********************
It should probably look like this: //************************* // A nice extended comment //************************* Benno
