test-bundle: split some variant in there own section
Same rational as the previous commit about test-bundle.t. These line are quite
volatile and having dedicated block will make their update clearer and simpler.
Differential Revision: https://phab.mercurial-scm.org/D12076
# genmerges is the workhorse of the test-merge-combination-*.t tests.
# Given:
# - a `range` function describing the possible values for file a
# - a `isgood` function to filter out uninteresting combination
# - a `createfile` function to actually write the values for file a on the
# filesystem
#
# it print a series of lines that look like: abcd C: output of -T {files}
# describing the file a at respectively the base, p2, p1, merge
# revision. "C" indicates that hg merge had conflicts.
