Mismatch between comment and actual code about when paths are made relative

[bjorn3]

The comment says it is done only for the short format:

backtrace-rs/src/capture.rs

Lines 493 to 496 in 57c7529

	// When printing paths we try to strip the cwd if it exists, otherwise
	// we just print the path as-is. Note that we also only do this for the
	// short format, because if it's full we presumably want to print
	// everything.

Which matches the printing code in libstd. The actual code however does it for the full format:

backtrace-rs/src/capture.rs

Lines 501 to 507 in 57c7529

	if style == PrintFmt::Full {
	if let Ok(cwd) = &cwd {
	if let Ok(suffix) = path.strip_prefix(cwd) {
	return fmt::Display::fmt(&suffix.display(), fmt);
	}
	}
	}

Looks like a regression in #526 which did a few changes to impl fmt::Debug for Backtrace which look unrelated to the issue the PR was addressing.
