Aaron Gyes c887e5dbde Fix apropos completions
The 'str' variable was apparently mistakenly removed by 49c5f96470.

Re-add it, and regex-escape it as well.

Allow completing on apropos <TAB> instaed of requiring an initial char.

Use __fish_apropos instead of apropos.

New regex to hopefully work on more platforms.

Explicitly use ^ instead of adding it at __fish_apropos
