`InteractivePrinter::print_snip` computes the snip separator width as
`term_width - panel_count - snip_left_count - title_count`. At `--terminal-width 1`
the panel is disabled and `title_count == 2`, so the subtraction underflows
`usize` (release has no overflow-checks, so it wraps to ~usize::MAX); `str::repeat`
then aborts with "capacity overflow" whenever a snip separator is emitted (two or
more disjoint line ranges, or a diff gap) — which the default style does.
Use `saturating_sub` for the repeat counts so they clamp to 0 instead of
underflowing. Added an integration test.
The Drop cleanup for Preprocessed inverted the exit-status check, so bat
emitted a warning when LESSCLOSE exited successfully and stayed silent on
failure. Align the condition with the intended behavior.
When bat is built without the `git` feature, `StyleComponent::Changes`
is not available. Add `#[cfg(feature = "git")]` guard so `--diff --plain`
works in both configurations.

Control characters displayed in caret notation (e.g. ^@ for NUL)
occupy 2 terminal columns, but the width calculation treated them
as 0-width. Add a char_width() helper that returns 2 for control
characters, fixing incorrect line wrapping with --binary=as-text.
Fixes#3631
When --plain is set (via CLI or config file), --diff output loses all
visual markers, making it indistinguishable from plain text. The diff
line filtering still works, but without Changes markers or Snip
separators the output is not useful.
Automatically include Changes and Snip style components when --diff is
active alongside --plain. This preserves the --plain intent (no grid,
no header, no line numbers) while keeping diff output readable.
Closes#3630
This would catch any dotfiles that end in "ignore", but not `.ignore`
Set as a lower priority rule (90 vs the usual 50) because it's a blanket
assignation. If there are conflict with other, more specific rules,
those will take precedence.
When a symlink name has no recognizable extension (e.g. Aliases/0install),
syntax detection fails because the symlink path doesn't match any syntax.
The target file may have a recognizable extension (e.g. Formula/zero-install.rb)
but was never consulted.
When path-based syntax detection fails with UndetectedSyntax, canonicalize
the path to resolve symlinks and retry detection with the target path.
This preserves existing behavior where the symlink path itself matches
(e.g. .ssh/config), since the original path is tried first.
Closes#1001
When BAT_CONFIG_DIR is set to the system config directory (e.g. /etc/bat),
both system_config_file() and config_file() resolve to /etc/bat/config.
The config file was read twice, causing clap errors for non-repeatable flags
like --italic-text.
Skip the user config read when it resolves to the same file as the system
config, using canonicalization to also handle symlinks.
Closes#3589
* feat(cli): add fallback syntax option
Expose a new fallback syntax CLI option so users can opt into syntax highlighting only when auto-detection fails.

* feat(syntax): apply fallback only after detection fails
Use the fallback syntax only when path and first-line detection fail, preserving existing behavior for detected files and explicit language selection.
