copies: clean up _related logic
The limit parameter was never actually used, since the only way the 4th case
could be reached was if f1r and f2r converged. The new code makes this clear,
and additionally reduces the conditional block to just 3 cases.
Put here definitions of blacklists for run-tests.py
Create a file per blacklist. Each file should list the names of tests that you
want to be skipped.
File names are meant to be used as targets for run-tests.py --blacklist
option.
Lines starting with # are ignored. White spaces are stripped.
e.g. if you create a blacklist/example file containing:
test-hgrc
# some comment
test-help
then calling "run-tests.py --blacklist blacklists/example" will exclude
test-hgrc and test-help from the list of tests to run.
