tr: -d a b c should show similar error as -d a b #5950
Description
This issue was mentioned by @BaherSalama in #5945.
GNU tr shows almost the same error for tr -d a b and tr -d a b c:
$ tr -d a b
tr: extra operand ‘b’
Only one string may be given when deleting without squeezing repeats.
Try 'tr --help' for more information.
$ tr -d a b c
tr: extra operand ‘b’
Try 'tr --help' for more information.
uutils tr, on the other hand, shows a clap error in the second case:
$ cargo run tr -d a b
tr: extra operand 'b'
Only one string may be given when deleting without squeezing repeats.
Try 'target/debug/coreutils tr --help' for more information.
$ cargo run tr -d a b c
error: unexpected value 'c' for '[sets]...' found; no more were expected
Usage: target/debug/coreutils tr [OPTION]... SET1 [SET2]
For more information, try '--help'.
