setup: update error message to be more meaningful
The error message shown when a flag is found when expecting a
filename wasn't clear as it didn't communicate what was wrong
using the 'suitable' words in *all* cases.
$ git ls-files
README.md
test-file
Correct case,
$ git rev-parse README.md --flags
README.md
--flags
fatal: bad flag '--flags' used after filename
Incorrect case,
$ git grep "some random regex" -n
fatal: bad flag '-n' used after filename
The above case is incorrect as "some random regex" isn't a filename
in this case.
Change the error message to be general and communicative. This results
in the following output,
$ git rev-parse README.md --flags
README.md
--flags
fatal: option '--flags' must come before non-option arguments
$ git grep "some random regex" -n
fatal: option '-n' must come before non-option arguments
