- update to 3.6.0:
* By default, Control-R now opens the command history in the pager,
* Abbrevations are more flexible
* The \\x and \\X escape syntax is now equivalent. \\xAB previously
behaved the same as \\XAB, except that it would error if the value “AB” was larger than “7f”
* The fish_git_prompt will now only turn on features if the appropriate
variable has been set to a true value (of “1”, “yes” or “true”)
instead of just checking if it is defined.
* Abbreviations are no longer stored in universal variables.
* The short option -r for abbreviations has changed from rename to regex,
for consistency with string.
* argparse can now be used without option specifications, to allow using
--min-args, --max-args or for commands that take no options
* set --show now shows when a variable was inherited from fish’s parent process,
which should help with debugging
* The read limit is now restored to the default when fish_read_limit is unset
* fish_clipboard_copy and fish_clipboard_paste can now be used in pipes
* A new variable, fish_cursor_selection_mode, can be used to configure whether
the command line selection includes the character under the cursor (inclusive) or not (exclusive)
* The complete-and-search binding, used with Shift-Tab by default,
selects the first item in the results immediately
* The key combination for the QUIT terminal sequence, often Control-Backslash (\\x1c),
can now be sused as a binding
* commandline gained two new options, --selection-start and --selection-end,
to set the start/end of the current selection
