avy-jump.el (avy-goto-char-timer): New command. Generalize
`avy-goto-char' and `avy-goto-char-2' with a timer.
* avy-jump.el (avy-timeout-seconds): New defcustom.
Fixes#13
With this change you can use `avy-goto-char' also to jump to the end of
some currently visible line. E.g., C-c j <return> (assuming C-c j is
bound to `avy-goto-char') makes all line endings jump targets.
`avy--overlay-at' had to be adapted so that the overlay at \n doesn't
make the line-break disappear.
`avy--overlay' had to be adapted in order not to put an overlay on the
char after (point-max) in case `avy--overlay-post' is used. (Honestly,
this feature is a bit awkward with 'post overlays where the jump
location is visualized as first char in the next line.)
* avy-jump.el (avy-dowindows): New macro.
(avy--regex-candidates): Use `avy-dowindows'.
(avy-goto-subword-0): Rely on `subword-backward'.
(avy--line): Use `avy-dowindows'.
Fixes#4
Before this commit, avy-goto-char with char ^ would inf-loop because the
resulting string "^" is treated as a regular expressions. However, with
the avy-goto-char* function, the char should be treated literally. For
example, in Clojure ^:foo is treated as metadata annotation and thus ^
is a likely jump target.
