[Bug]: Comments in bash are not logged

[TopherIsSwell]

What did you expect to happen?

I expected this to function like bash history and record comments in the history.

Sometimes I begin writing a complex command and then realize I need more information before I can finish it, so I add a pound at the beginning of the command and press enter so its in my bash history. I collect the needed information, then I Ctrl-R to bring up the commented command and I remove the comment and finish the command.

Contrived example:

$ #for host in prod1e{1,2,3}-nginx-{1,2}; do rsync -avu "$host":/dev/ ...
$ ls /dev
$ for host in prod1e{1,2,3}-nginx-{1,2}; do rsync -avu "$host":/dev/cpuinfo "./$host-cpuinfo"; done

What happened?

Commands beginning with # are excluded from the history. However commands with a comment at the end of the line are included which is expected. They don't show up in Ctrl-R search. They do show up in bash's session history (I've disabled the keybinding in atuin, and when I press to navigate history, it's using bash and I see the commented commands).

$ echo comment #comment
comment

$ echo comment follows
comment follows

$ #My little comment

$ echo comment before this
comment before this

$ sqlite3 ~/.local/share/atuin/history.db 'select command from history order by timestamp desc limit 5;'
sqlite3 ~/.local/share/atuin/history.db 'select command from history order by timestamp desc limit 5;'
echo comment before this
echo comment follows
echo comment #comment
PS1="\$"

Requested fix

As a non-breaking fix, if there was a log_comments option in the config, then people who desire to have comments in their history would have the option without changing the default behavior for anyone who's come to expect/rely on comments being omitted.

As described in README, bash-preexec has a limitation. The behavior reported in this PR is actually the limitation. For details, ee [Bash]-[bash-preexec] on Installing the shell plugin - Atuin Docs. Check also the upstream issue rcaloras/bash-preexec#158.
