Only the first line of a multi-line command is recorded.

[shelvacu]

Run a command like:

echo '1
2
3'

and ash will only record echo '1

This happens because read only reads the first line, see

advanced-shell-history/shell/bash

Line 136 in e43e312

read -r cmd_no start_ts cmd <<< "$( builtin history 1 )"

advanced-shell-history/shell/common

Line 111 in e43e312

read -r no start end cmd <<< "$( __ash_last_command )"

advanced-shell-history/shell/zsh

Line 67 in e43e312

read -r cmd_no cmd <<< "$( builtin history -1 )"

I've only tested this in bash, but if zsh's read works the same then it will have the same bug.

This could be somewhat mitigated in bash with shopt -u cmdhist, which will save each line as a separate command.

This could be solved by moving the 'parsing' code to C++/python and doing builtin history 1 | __ash_log --history-from-stdin or something
