Greetings,
We are in a package freeze with Grep 2.19.
For 2.20, are any of the following a required upgrade for grep which
would be a critical issue for our release?

grep: fix --max-count=N (-m N) to stop reading after Nth match
With --max-count=N (-m N), grep is supposed to stop reading
input
after it has found the Nth match. However, a recent context-
related change made it so grep would always read to end of
file.
* src/grep.c (prtext): Don't let a negative "out_after" value
make "pending" line count negative.
* tests/max-count-overread: New test, for this.
* tests/Makefile.am (TESTS): Add it.
* NEWS (Bug fixes): Mention it.
* THANKS: Add names of two recent bug reporters.
This bug was introduced by commit v2.18-139-g5122195.
Reported by Marc Aldorasi in http://bugs.gnu.org/17640.

dfa: fix off-by-one under-allocation from recent change
Commit v2.19-10-gc32ff67 mistakenly made this change:
-realloc_trans_if_necessary (d, 1);
+realloc_trans_if_necessary (d, 0);
which led to a heap buffer overflow.
* src/dfa.c (dfaexec): Allocate space for one state, as before.

dfa: fix bug with regex containing multiple begin/end-line
constraints
grep -E 'a(b$|c$)' would mistakenly match "aa".
* src/dfa.c (dfamust): When resetting 'is' in OR, also reset
'begline' and 'endline' of 'must'.
* NEWS (Bug fixes): Mention it.
This bug was introduced via commit v2.18-85-g2c94326.

dfa: simplify building initial state
build_state_zero doesn't need the struct dfa to be initialized,
so remove the initialization and simplify.
* src/dfa.c (build_state_zero): Remove.
(dfaexec): Call realloc_trans_if_necessary and build_state
directly.
dfa: revert "grep: do not count newline before the start of
buffer"
This reverts commit 5dc3af2806d21455b818be3f9da26c372e4a7f8d.
The previous change renders that commit unnecessary.
Sincerely,
William Harrington
