Perhaps someone can explain to me what I missed in the posted question that was glaringly apparent to everyone else. When I first saw it there were some things IMHO that made it a great candidate for "unclear what you are asking status" for it seemed the OP was looking for an answer to something that was not defined very well and IMHO had some glaring falsehoods like "Gedit always defaults to Matlab syntax highlighting". (VTC not possible due to bounty assignment)
Even one of the questions linked as similar states "Until you save a document in gedit, syntax highlighting is turned off" and experience tells me that when I open an unrecognized (unknown mime-type) file it defaults to plain text. So, I answered the question asked. The answer that was accepted is clearly superior to mine in that it seems to have answered what the OP intended to ask. It's certainly apparent after the fact what the OP was looking for but without that as a signpost? What did I miss in the question that makes it a good question? The comment (which I clearly missed) where the OP finally actually describes his problem wasn't edited into it as it should have been. In fact, I can't find a single response to any of the questions asked about this question edited into the OP.
Note: This is not intended in anyway to disparage the accepted answer (which in point of fact I upvoted as well)
I'm just wondering if I'm incorrect in my assumptions that A) The question is poorly crafted and B) Pertinent information should be edited into the original post
Please tell me what you think as it will have bearing on my future work. If I'm wrong about A) I need to adjust my quality standards accordingly and if I'm wrong about B) I can stop wasting my precious time encouraging OP's to edit pertinent information into there posts.
Thanks in advance!
