Clean up the ftplugin a bit. Use the save_cpo pattern to ensure cpo is
set appropriately, and define a b:undo_ftplugin.

Change the b:match_words definition to match else/else if.

Subject: [PATCH 05/33] Improve fish#Indent()

- Fix: multiline strings should not be modified.
- Fix: "end" is always decreased by one.
- Fix: "case" and "else" are always decreased by one.
- Fix: continued lines are not treated differently.
- Fix: "if", "while", etc followed by "begin" should increment next line
  by two instead of by one.
- Fix: "case" should be one more than "switch".
- Fix: multiline strings and continued lines are considered in the
  calculations for the next line.

Subject: [PATCH 06/33] Small improvements.

- funced and fish_indent always uses tabs for indentation, use
  fish#Indent() to fix it. Works better with the improved fish#Indent().
- ftdetect should contain filetype detection code. Move autocmds to
  plugin/fish.vim.
- Match new funced temp file name.
- Add "else", "else if" and "case" to b:match_words to follow what's
  used by Vim's ftplugins.

blankname:
- dropped the syntax changes (cc: dag/vim-fish#28)

Subject: [PATCH 11/33] Remove '/' from iskeyword so that 'w' doesn't skip over
 entire paths.

I didn't remove the iskeyword definition entirely because I believe including
'_' and '.' is still useful.

Use 'syntax iskeyword @,48-57,-,_,.,/' in the syntax definitions so that '/' is
still matched by syntax patterns that use '\k'.
