avy-goto-char-in-line fails in inferior-REPL prompts

[bymoz089]

avy-goto-char-in-line fails when point is at the beginning of a REPL prompt.
Reason is, those pompts are fields and regexp-quote can't jump over fields.

Possible Solution: set variable inhibit-field-text-motion to 't.

(defun avy-goto-char-in-line (char)
  "Jump to the currently visible CHAR in the current line."
  (interactive (list (read-char "char: " t)))
  (let ((inhibit-field-text-motion t))
    (avy-with avy-goto-char
      (avy-jump
       (regexp-quote (string char))
       :beg (line-beginning-position)
       :end (line-end-position)))))

How to reproduce the bug:

1. start inferior lisp repl M-x ielm
2. enter some random text at the promt (to be able jump to it later)
3. jump with avy-goto-line to a line, which contains a repl prompt. So point is at E of ELISP>
4. try to call avy-goto-char-in-line (it wil fail, with "zero candidates" message)

Edit: this issue is present in all comint-derived modes like M-x shell M-x ielm and in slime.

Question is, why would you want to go there? Suppose you have:

ELISP> emacs

Pressing C-a takes you to the beginning of emacs, not the beginning of ELISP>. We could also advice beginning-of-line to bind inhibit-field-text-motion, but why? The current behavior is on purpose. Unless I'm missing something.

My point lands very often at the beginning of those lines, as described in the reproduction example.
But since you wrote: the behavior is intended, I'll close this issue and write a small wrapper function for the avy-goto-char-in-line command into my initrc.
