Re: How can I create a filetype association that uses the filename's extension?

Mmm. Given how traditional it is to use extensions as clues to the
file type (a 'soft' indication on Linux, a 'hard' indication on
Windows), I do think the Open With box should recognise that the
extension may be important, even if it's unregistered. Offer three
options, say:

* Just this once
* Remember for all plain text files called *.extension
* Remember for all plain text files

I've just filed a bug to that extent: 639170. --- And promptly marked
it a duplicate of 596382.

(The other guy wrote "suffix", and I searched for "extension", hence
why I didn't spot it 'till after I reported it.)

I find them tolerable. ;-) Thanks for the links, certainly; I'm sure
I'll work it out from there.
