24h expire time limit makes seashell unpractical for real life use

I often need to share execution logs for code reviewing, as a proof that the new behaviour works.

Now the big problem is that code reviewing take time, in 99% of cases more than 24h, probably even more than a week.

Usually I would use gists but those also have two major limitations:

• not coloured, so much harder to read long logs (like ansible output)
• not streamed, meaning that they will not be accessible until the command finishes, which can slow you down a lot, especially when the runnings command takes 30-2h to run on average.
