Revision 55672a39b4e0f82e6f997879724ea37ca7e0d765 authored by Junio C Hamano on 09 May 2016, 18:36:09 UTC, committed by Junio C Hamano on 09 May 2016, 19:32:42 UTC
We never used the "letters" form since we came up with "test_seq" to
replace use of non-portable "seq" in our test script, which we
introduced it at d17cf5f3 (tests: Introduce test_seq, 2012-08-04).

We use this helper to either iterate for N times (i.e. the values on
the lines do not even matter), or just to get N distinct strings
(i.e. the values on the lines themselves do not really matter, but
we care that they are different from each other and reproducible).

Stop promising that we may allow using "letters"; this would open an
easier reimplementation that does not rely on $PERL, if somebody
later wants to.
