I have disovered a regression in commit abe92e8010ab ("Prefer idx_t,
ptrdiff_t to lin") while I was running MariaDB tests. The regression is
related to a diff file [1], where the patch fails to apply it with
following error:
patch: **** '---' expected at line 2 of patch
To illustrate the issue, I have attached a git patch containing a
testcase with simplified reproducer.
