Enable ui.formatted because pager won't fire without it, and set up | ||||
pager and tell it to use our fake pager that lets us see when the | ||||
pager was running. | ||||

A command that asks for paging using ui.pager() directly works: | ||||
$ hg blame a | ||||
paged! ' 0: a\n' | ||||
paged! ' 1: a 1\n' | ||||
paged! ' 2: a 2\n' | ||||
paged! ' 3: a 3\n' | ||||
paged! ' 4: a 4\n' | ||||
paged! ' 5: a 5\n' | ||||
paged! ' 6: a 6\n' | ||||
paged! ' 7: a 7\n' | ||||
paged! ' 8: a 8\n' | ||||
paged! ' 9: a 9\n' | ||||
paged! '10: a 10\n' | ||||
but not with HGPLAIN | ||||

0: a | ||||
1: a 1 | ||||
2: a 2 | ||||
3: a 3 | ||||
4: a 4 | ||||

7: a 7 | ||||
8: a 8 | ||||
9: a 9 | ||||

1: a 1 | ||||
2: a 2 | ||||
3: a 3 | ||||
4: a 4 | ||||
