commit 1048a870e3b6973a5be1193f3b45e6e867e8e1c0 Author: Daniel Tameling <[email protected]> AuthorDate: 2023-07-13 20:06:31 +0000 Commit: Dag-Erling Smørgrav <[email protected]> CommitDate: 2023-07-13 21:35:23 +0000 xargs: disallow -R0 and -L0 Both cases were interpreted as these flags are unset. This meant that -R0 got converted to -R5 and that -L0 didn't have any effect at all. Since make at most 0 replacements isn't useful and since call utility for every 0 lines read doesn't make sense, throw an error for these two cases.
