[PATCH/RFC] setup: update error message to be more meaningful

[Kaartic Sivaraam]

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.

Correct case,

        $ git rev-parse commit.c --flags
        commit.c
        --flags
        fatal: bad flag '--flags' used after filename

Incorrect case,

        $ git grep "test" -n
        fatal: bad flag '-n' used after filename

Change the error message to be general and communicative. This results
in the following output,

        $ git rev-parse commit.c --flags
        commit.c
        --flags
        fatal: found flag '--flags' in place of a filename

        $ git grep "test" -n
        fatal: found flag '-n' in place of a filename
