For example, given `-dump-input-context=3 -vv`, the following now
shows more leading context for the error than requested because a
leading ellipsis would occupy the same number of lines as it would
elide:
```
<<<<<<
1: foo6
2: foo5
3: foo4
4: foo3
5: foo2
6: foo1
7: hello world
check:1 ^~~~~
check:2 X~~~~ error: no match found
8: foo1
check:2 ~~~~
9: foo2
check:2 ~~~~
10: foo3
check:2 ~~~~
.

; Input file, check file, and directives for checking the size of the context.
|
|
;
|
|
; These are designed to be used with -dump-input=fail -vv.
|
|
;
|
|
; In the resulting input dump, there are three potential ellipses:
|
|
;
|
|
; - S: At the start of the input.
|
|
; - M: Between two input lines included by the filter.
|
|
; - E: At the end of the input.
|
|
;
|
|
; They are all present at -dump-input-context=4. One becomes useless each time
|
|
; -dump-input-context is incremented beyond that because then that ellipsis
|
|
; becomes equal to or larger than the input lines it elides.
