An interim report.
It indeed is that merge with the topic. I rebuilt an equivalent of
'master' without that topic on top of v2.17.0 and tried the same
merge of sb/filenames-with-dashes fd055186 ("replace_object.c:
rename to use dash in file name", 2018-04-10) topic into pu^
35f7512e ("Merge branch 'fg/completion-external' into pu",
2018-04-11), and that version of Git does not exhibit the problem.
I do not yet know which one of the ~30 individual commmits is the
real culprit, but in the meantime, I'll revert the merge out of
'master' and push the result out, so that real Git-using projects
won't get silent mismerges. Those who run in-house version of Git
that is based on anything newer than the released version may want
to do the same.
Sorry for the crappy 'master' X-<.
