            Bug ID: 46633
           Summary: Invalid handling of AfterControlStatement: MultiLine
           Product: clang
           Version: 10.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: varqox at gmail.com
                CC: djasper at google.com, klimek at google.com,
                    llvm-bugs at lists.llvm.org

With the following .clang-format file:
====================
Language:        Cpp
BreakBeforeBraces: Custom
BraceWrapping:
  AfterControlStatement: MultiLine
ColumnLimit:     80
IndentWidth:     4
====================
running clang-format on
====================
void foo() {
    if (very_long_variable_name or other_very_long_variable_name or
        long_variable)
    {
        return;
    }
}
====================
produces:
====================
void foo() {
    if (very_long_variable_name or other_very_long_variable_name or
        long_variable) {
        return;
    }
}
====================
Expected output: the same as input.
Command used: clang-format bug.cc
clang-format version: 10.0.0

Additional notes:
If you change "long_variable)" to "long_variable123)" or "long_variab)"
formatting is correct -- the brace gets wrapped. So it seems that if an if
condition ends slightly after the column limit (if placed in a single line),
then it is formatted incorrectly.
