--- Comment #1 from Philip Hazel <Philip.Hazel@???> ---
The idea of this test is to check that the standard input is left in the right
place when pcre2grep stops because it has reached the -m limit. The "a" line is
generated by the "head -1" command when run under Linux (which is all I have):
$ (./pcre2grep -m1 -A3 '^match'; echo '---'; head -1) < testdata/grepinput
match 1:
a
match 2:
b
---
a
Looks like this is yet another Linux/BSD difference. Sigh. I think the relevant
code is around line 2589 in pcre2test.c:
/* If the -m option set a limit for the number of matched or non-matched
lines, check it here. A limit of zero means that no matching is ever done.
For stdin from a file, set the file position. */
if (count_limit >= 0 && count_matched_lines >= count_limit)
{
if (frtype == FR_PLAIN && filename == stdin_name && !is_file_tty(handle))
(void)fseek(handle, (long int)filepos, SEEK_SET);
rc = (count_limit == 0)? 1 : 0;
break;
}
