Note: There is an alternative change that turns
-asmapinto a bool option and adds a-asmapfileoption: #33631 Please indicate with your conceptual review which option you prefer, thanks!This changes the behavior of the
GetPathArgfunction to better work with the behavior of-asmap. When a path arg is given "1" (for example -asmap=1), this would currently be interpreted as a path but should be interpreted as using the arg without a parameter which activates the fallback. There is no explicit test added here because this is tested implicitly in the tests added in #28792.Also improves the documentation of the
-asmapdefault behavior.See #33386 for further discussion. Closes #33386
