//! ZLE delete-to-char / zap-to-char widgets — port of
//! `Src/Zle/deltochar.c` (141 lines).
//!
//! C source has zero `struct ...` / `enum ...` definitions. The
//! Rust port matches: zero types. The two static `Widget`
//! variables (`w_deletetochar`, `w_zaptochar`) are local to C's
//! module-loader path and don't translate — zshrs wires the two
//! widgets through `extensions/widget.rs` at build time.


/// Port of `deltochar(UNUSED(char **args))` from `Src/Zle/deltochar.c:38`. The shared
/// body behind both the `delete-to-char` and `zap-to-char` widgets:
/// reads the next char from input, then for each repeat of `zmult`
/// scans the buffer toward that target and kills the spanned text
/// (forward when `zmult >= 0`, backward when `zmult < 0`). The
/// "zap" mode (binding name `zap-to-char`) includes the target
/// char itself in the killed range.
///
/// C signature: `static int deltochar(char **args)` (args UNUSED).
/// Returns 0 on success (target found, kill performed), 1 on
/// failure (target not in buffer).
/// WARNING: param names don't match C — Rust=(zle) vs C=(args)
