I didn't get a reply. Here's what I've come up with so far (using
clang 18 from pkgsrc).
 Thomas

# 80 characters line length
ColumnLimit: 80
# if comments get too long, fmt them.
ReflowComments: true
# default indentation level
IndentWidth: 8
# also for struct initializers
BracedInitializerIndentWidth: 8
# prefer using tabs to spaces when indenting
UseTab: ForContinuationAndIndentation
# indent 1 space more per #if-level
PPIndentWidth: 1
# and put the space after the hash but before the keyword (i.e., "# if")
IndentPPDirectives: AfterHash
# backslashes at end-of-line are aligned, but as far left as possible
AlignEscapedNewlines: Left
# not supported in clang-format 18, would include the last line (without backslash) in the offset consideration
#AlignEscapedNewlines: LeftWithLastLine
#
# if function arguments get too long, start new line indented by 4
AlignAfterOpenBracket: DontAlign
ContinuationIndentWidth: 4
# but keep first parameters on the first line
AllowAllParametersOfDeclarationOnNextLine: False
AllowAllArgumentsOnNextLine: false
# for struct's etc. use 8 characters indent as well
ConstructorInitializerIndentWidth: 8
# newline before "{" except for functions 
BreakBeforeBraces: WebKit
# for functions, add newline after return type
AlwaysBreakAfterReturnType: TopLevelDefinitions
# align structure elements to the right
AlignArrayOfStructures: Right
