Shell commands have a " " prefixed, breaking (some) history

[klausman]

Step 1: Provide a summary of your problem

All commands in a YAML file have a " " (space, 0x20) prefixed, which breaks history for people who have bash set to omit space-prefixed commands form history. If I wanted that, specifying a space in the config would be the thing to do.

Step 2: Provide tmuxp details

• Include output of tmuxp debug-info

Step 3: Describe the problem:

Steps to reproduce:

~ $ cat bla.yaml 
session_name: shorthands
windows:
  - window_name: long form
    panes:
    - shell_command:
      - echo 'did you know'
      - echo 'you can inline'
    - shell_command: echo 'single commands'
    - echo 'for panes'
$ tmuxp load bla.yaml

Observed Results:

• What happened? This could be a description, log output, etc.

 echo 'did you know'
 echo 'you can inline'
workdog ~ $  echo 'did you know'
did you know
workdog ~ $  echo 'you can inline'
you can inline
workdog ~ $ 






──────────────────────────────────────────────────────────────────────────────────
 echo 'single commands'
workdog ~ $  echo 'single commands'
single commands
workdog ~ $ 
──────────────────────────────────────────────────────────────────────────────────
 echo 'for panes'
workdog ~ $  echo 'for panes'
for panes
workdog ~ $ 

[workdog]0:long form*           ```
#### Expected Results:
  * What did you expect to happen?

#### Relevant Code:

Note how all the echo commands have space in front of them. Since I have shopt -s ignorespace (for reasons unrelated to tmuxp), it means that I can't arrow-up to rerun those commands. Wrapping the commands like this: - "echo bla" does not help.
