Basically, you can reply to the bug-bash list instead of directly
replying to the individuals.

It depends on what would be the result that you expect.
a) If you expect the words obtained from the expanded result of $(fc
-l -10), the first picture you have attached in the previous reply [I
attach it again for bug-bash list: 66de9...@7e85d46f.87d12062.jpg] is
the expected one. In this case, we can just pass the literal $(fc -l
-10) to compgen as I have replied.
b) If you expect the lines obtained from the expanded result of $(fc
-l -10), you need to set IFS=$'\n'. So,
IFS=$'\n' compgen -W '$(fc -l -10)'

c) If you expect the literal $(fc -l -1), you need to quote the word as
compgen -W '\$\(fc\ -l\ -1\)'
or
compgen -W \''$(fc -l -1)'\'
or
tmp='$(fc -l -1)'
compgen -W '"$tmp"'
What is the result you actually would like to achieve?
