Remove '--quiet' feature of abbreviations
Per code review, this is too risky to introduce now. Leaving the feature in history should want want to revisit this in the future.

|

- Matching tokens may be described using a regular expression instead of a literal word
|
||||
- The replacement text may be produced by a fish function, instead of a literal word
|
||||
- They may optionally only trigger after space, or after enter
|
||||
- They may optionally run "quietly," without visibly modifying the command line
|
||||
- They may position the cursor anywhere in the expansion, instead of at the end

Abbreviations may expand either after their word is entered, or if they are executed with the enter key. The ``--trigger-on`` option allows limiting expansion to only entering, or only executing.
|
||||
|
||||
By default abbreviations print the new command line after being entered. The ``--quiet`` option causes abbreviations to expand silently.
|
||||
|
||||
Combining these features, it is possible to create custom syntaxes, where a regular expression recognizes matching tokens, and the expansion function interprets them. See the `Examples`_ section.
|
||||
|
||||
Abbreviations may be added to :ref:`config.fish <configuration>`. Abbreviations are only expanded for typed-in commands, not in scripts.

|
||||
|
||||
``abbr --add`` creates a new abbreviation. With no other options, the string **NAME** is replaced by **EXPANSION**.
|
||||
|
||||
With **--quiet**, the expansion occurs without printing the new command line. The original, unexpanded command is saved in history. Without **--quiet** the new command line is shown with the abbreviation expanded. If a **--quiet** abbreviation results in an incomplete command or syntax error, the command line is printed as if it were not quiet.
|
||||
|
||||
With **--position command**, the abbreviation will only expand when it is positioned as a command, not as an argument to another command. With **--position anywhere** the abbreviation may expand anywhere in the command line. The default is **command**.
|
||||
|
||||
With **--regex**, the abbreviation matches using the regular expression given by **PATTERN**, instead of the literal **NAME**. The pattern is interpreted using PCRE2 syntax and must match the entire token. If multiple abbreviations match the same token, the last abbreviation added is used.
|
||||
|
||||
With **--set-cursor**, the cursor is moved to the first occurrence of **SENTINEL** in the expansion. That **SENTINEL** value is erased.
|
||||
|
||||
With **--trigger-on entry**, the abbreviation will expand after its word or pattern is ended, for example by typing a space. With **--trigger-on exec**, the abbreviation will expand when the enter key is pressed. These options may be combined, but are incompatible with **--quiet**. The default is both **entry** and **exec**.
|
||||
With **--trigger-on entry**, the abbreviation will expand after its word or pattern is ended, for example by typing a space. With **--trigger-on exec**, the abbreviation will expand when the enter key is pressed. These options may be combined. The default is both **entry** and **exec**.
|
||||
|
||||
With **-f** or **--function**, **EXPANSION** is treated as the name of a fish function instead of a literal replacement. When the abbreviation matches, the function will be called with the matching token as an argument. If the function's exit status is 0 (success), the token will be replaced by the function's output; otherwise the token will be left unchanged.

This first creates a function ``last_history_item`` which outputs the last entered command. It then adds an abbreviation which replaces ``!!`` with the result of calling this function. The ``--quiet`` option causes the expansion to happen without visibly modifying the text. Taken together, this implements the ``!!`` history expansion feature of bash.
