Subject: [PATCH] split: do not shrink hold buffer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* src/split.c (line_bytes_split): Do not shrink hold buffer.
If it’s large for this batch it’s likely to be large for the next
batch, and for ‘split’ it’s not worth the complexity/CPU hassle to
shrink it.  Do not assume hold_size can be bufsize.
