xargs -S limit is far too low #13
Description
xargs documents that -S (replsize) defaults to 255 bytes. That is a fine figure for 1970, but 255 MiB would be a better default in 2025. This limits the size of an argument that xargs can replace with -I. POSIX doesn't even specify -S, presumably because requiring the user to adjust this is a microoptimization that no longer makes sense.
