bug#2148: In shell mode, comint-send-input seems to cut off at 254 characters |

I attempted to do this command in shell mode:
echo
_234567_10_234567_20_234567_30_234567_40_234567_50_234567_60_234567_70_234567_80_234567_90_23456_100_23456_110_23456_120_23456_130_23456_140_23456_150_23456_160_23456_170_23456_180_23456_190_23456_200_23456_210_23456_220_23456_230_23456_240_23456_250_23456_260
The immediate output was:
0_23456_260: Command not found.
but when I hit enter again without typing anything else, I got:
_234567_10_234567_20_234567_30_234567_40_234567_50_234567_60_234567_70_234567_80_234567_90_23456_100_23456_110_23456_120_23456_130_23456_140_23456_150_23456_160_23456_170_23456_180_23456_190_23456_200_23456_210_23456_220_23456_230_23456_240_23456_25
So the first 254 characters I typed got held back, and the additional 11
characters were sent to the inferior shell. Further, the held back characters
were then sent when I pressed enter again.
So this is what the buffer looked like:

I would count this as very unexpected and dangerous behaviour.
