Add '--' to all calls to string

[matiasjrossi]

Description

Initially looked into this to solve the following bug:

❯ ls \
      --foobarstring trim: Unknown option '--foobar'

~/.config/fish/functions/__abbr_tips_bind_newline.fish (line 1):
in command substitution
	called on line 3 of file ~/.config/fish/functions/__abbr_tips_bind_newline.fish
in function '__abbr_tips_bind_newline'

(Type 'help string' for related documentation)

ls: unrecognized option '--foobar'
Try 'ls --help' for more information.

Then went ahead and made the same changes across the plugin.

With the changes to functions/__abbr_tips_bind_newline.fish the error message is prevented:
