fish_clipboard_paste: trim indentation when pasting multiple lines When pasting a multiline command with indented blocks, extra indentation from spaces, or tabs, is generally undesirable, because fish already indents pipes and blocks. Discard the indentation unless the cursor or the pasted part is inside quotes. Users who copied fish_clipboard_paste need to update it because __fish_commandline_is_singlequoted had an API change and was renamed.

function __fish_tokenizer_state --description "Print the state of the tokenizer at the end of the given string"
Auto-escape pastes inside single-quotes This is to make pasting literals easier. When a user pastes something, we normally take it as-is. The exception is when a single-quote is open, e.g. the current token is foo'bar When something is pasted here, we escape single-quotes (`'`) and backslashes (`\\`), so typing a `'` after it will turn it into a literal token. Fixes #967.

# Go through the token char-by-char in a state machine.
# The states are:
# - normal - no quoting is active (the starting state)
# - single - open single-quote
# - double - open double
# - escaped - open \\ - the next character is non-special
# - single-escaped - open \\ inside single-quotes
# - double-escaped - open \\ inside double-quotes
Fix clipboard_paste nicer Instead of hacking in arbitrary characters to avoid splitting, just use `string collect`. This reverts commit e450190d50aecefd26f932f6868bb128ae817441. Fixes #7782, but nicer.
