revset: optimize 'or' operation of trivial revisions to a list
As seen in issue4565 and issue4624, GUI wrappers and automated scripts are
likely to generate a long query that just has numeric revisions joined by 'or'.
One reason why is that they allows users to choose arbitrary revisions from
a list. Because this use case isn't handled well by smartset, let's optimize
it to a plain old list.
Benchmarks:
1) reduce nesting of chained 'or' operations
2) optimize to a list (this patch)
revset #0: 0 + 1 + 2 + ... + 1000
1) wall 0.483341 comb 0.480000 user 0.480000 sys 0.000000 (best of 20)
2) wall 0.025393 comb 0.020000 user 0.020000 sys 0.000000 (best of 107)
revset #1: sort(0 + 1 + 2 + ... + 1000)
1) wall 0.035240 comb 0.040000 user 0.040000 sys 0.000000 (best of 100)
2) wall 0.026432 comb 0.030000 user 0.030000 sys 0.000000 (best of 102)
revset #2: first(0 + 1 + 2 + ... + 1000)
1) wall 0.028949 comb 0.030000 user 0.030000 sys 0.000000 (best of 100)
2) wall 0.025503 comb 0.030000 user 0.030000 sys 0.000000 (best of 106)
