autojump.bash: fix bash PROMPT_COMMAND space syntax error

[parkermo]

Every execution of $PROMPT_COMMAND throws a syntax error for me using bash version 5.2.37(1)-release (x86_64-pc-linux-gnu). The syntax error message goes away if I remove the space before the semi-colon in the modified PROMPT_COMMAND.

In ~/.bash_aliases, I have: . /usr/share/autojump/autojump.sh.

Broken:

~$ bash --version

bash: PROMPT_COMMAND: line 19: syntax error near unexpected token `;'
bash: PROMPT_COMMAND: line 19: ` ; autojump_add_to_database'
~$ echo $PROMPT_COMMAND
__bp_precmd_invoke_cmd history -a ; autojump_add_to_database __bp_interactive_mode
bash: PROMPT_COMMAND: line 20: syntax error near unexpected token `;'
bash: PROMPT_COMMAND: line 20: ` ; autojump_add_to_database'

(Line number increases with each prompt that your terminal generates, so it does not point to autojump.sh line number).

After making this change:

~$ bash --version

I noticed this only recently, so it could be related to an update in Bash.
