[PATCH v9 2/3] t7507-commit-verbose: make test suite use write_script

["SZEDER Gábor" <szeder@ira.uka.de>]

> Also remove test_set_editor from global scope and use it in whichever
> test it is required.

Why?

test_set_editor sets and exports shell variables.  Since you don't
invoke test_set_editor in a subshell, after the first invocation the
editor will be part of the global scope anyway.

Also missing signoff.

Our test lib offers the test_line_count helper function, which
outputs a helpful error message in case the number of lines do not
match.

The original didn't check the number of lines.  This change is not
mentioned at all in the commit message.
