Isn't that what compctl -X is for?

compctl -P - -X 'A <num>  - show <num> lines of context after match
B <num>  - show <num> lines of context before match
<num>    - show <num> lines of context before and after match
C        - show 2 lines of context before and after match
E        - extended regular expression (egrep)
F        - fixed string expression (fgrep)
G        - basic regular expression (grep) 
L        - print only the names of files that do NOT have a match
V        - print version number
b        - prefix output with byte offset of each line
c        - print only a count of matching lines
h        - do not prefix lines with file names
i        - case insensitive match
l        - print only the names of files that have a match
n        - prefix output with line number of each line
q        - print nothing (set exit status only)
s        - do not print error messages
v        - select lines that DO NOT match the expression
w        - match expression against whole words only
x        - match expression against whole lines only
f <file> - read expressions from file <fil>
e        - expression follows' \
    -k '(A B C E F G L V b c e f h i l n q s v w x)' grep

} This would come in handy for all completion of numbers like job numbers,
} process ids, ...

The problem with job numbers and process IDs is that you have to generate
the explanation on the fly.  Maybe what we need is a way to run a function
to provide the -X output, rather than having only a fixed string.
