The "like" operator in AbuseFilter started behaving differently, after Bug 66930 was resolved in https://gerrit.wikimedia.org/r/#/c/141483/ .
Currently:
"a-b" like "a-b"
=> false
Previously:
"a-b" like "a-b"
=> 1
I believe this was an unexpected side effect. At least the change was not documented anywhere to prevent breakage of existing filters.

Bug 66935, it seems.
Probably Ori and Aaron to comment here, as that patch seems to have created this problem?
Change 145697 had a related patch set uploaded by Ori.livneh:
Fix double escaping in AFPData::keywordLike()
Sorry for not including this first, but " " seems to need the same fix.
"a b" like "a b" => false
