Pull request: Cheat with multiline comment and multiline command

[QiangF]

Hello sir,
Sorry I don't have time to learn to create a pull request. I've made a small improvement over your cheat. Except what said in the title, it will also put the cheat and user input into the bash history, also added a command sucheat. With it you can run command like the embed cheat, which I can't get to work in one line.
I am still trying to get the default value for a variable to work.
My cheat.sh is at https://gist.github.com/QiangF/565102ba3b6123942b9bf6b897c05f87

The format for a cheat is:
comment

command

variables

No, wait, don’t close this! I was going to look at this, only I couldn’t find the time and it got pushed back further and further on my agenda… sorry :(

• I don’t really like the multiline format with explicit separator lines. However, multi-line support in general is probably a good thing. What if we use read instead of read -r? Then you can use a backslash to continue the current line:

  Force (unreachable NFS) Lazy unmount:\
   Detach the filesystem from the filesystem hierarchy now, and cleanup all\
   references to the filesystem as soon as it is not busy anymore.
  umount -f -l "$mounting_point"
  mounting_point:mounting point
  

  (Note that the line breaks won’t appear in the read content.)

• Adding the cheat to history sounds like a good idea, but why do you also add the cheat $* line to history? As far as I can tell, that should already be present in the history since that’s the command you just ran.

• I don’t really see the need for sucheat. Your embed example can, I think, be written in one command as:

  sudo DISPLAY=:0 Xephyr :1 -fullscreen -reset -terminate & export DISPLAY=:1
