Subject: object-name: turn INTERPRET_BRANCH_* constants into enum values
X-Git-Tag: v2.54.0-rc0~13^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c5fc44f54595f123c277e5839cbafa1bc9c8c050;p=thirdparty%2Fgit.git

object-name: turn INTERPRET_BRANCH_* constants into enum values

Replace the INTERPRET_BRANCH_* preprocessor constants with enum
values and use that type where these flags are stored or passed
around.

These flags describe which kinds of branches may be considered during
branch-name interpretation, so represent them as an enum describing
branch kinds while keeping the existing bitmask semantics and
INTERPRET_BRANCH_* element names.
