Problem / Steps to reproduce

Binding a custom action to ctrl-h seems to be ignored (backward-delete-char is enforced). This may be related to

fzf/CHANGELOG.md

Lines 252 to 255 in 8cdfb23

	### 7. Added key support for `--bind`
	Pull request [#3996](https://github.com/junegunn/fzf/pull/3996) added support
	for many additional keys for `--bind` option, such as `ctrl-backspace`.

since I only observe this behavior when upgrading from 0.65 to 0.66.

The following test does not bind ctrl-h:up (ctrl-l:down works as expected):

seq 4 | env --ignore-environment <path to fzf> --bind ctrl-h:up,ctrl-l:down

Looks like it is overridden by ctrl-backspace. So for now, a workaround is to write ctrl-backspace (or ctrl-bs) instead of ctrl-h.

I can confirm that also fixes the issue for me. Sorry for the inconvenience and thanks for the fix!

No problem! I appreciate your contribution.
