Subject: When adding boolean keywords for typo correction, add either "bool" or
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=07f4a06c402a2ccdd9eae7a3d710990b22040001;p=clang

When adding boolean keywords for typo correction, add either "bool" or
"_Bool" (depending on dialect), but not both, since they have the same
edit distance from "Bool".
