默认怎么转换？What does the default do?

默认是「固定连续空格（行首）」：只转换每行开头连续的空格，每满「空格/Tab」个换成一个 Tab，余下不足一个 Tab 的空格保留在 Tab 后面（例如宽度 4 时 6 个空格 → 1 个 Tab + 2 个空格）；行内空格不动。The default is "Fixed run (leading)": only the run of spaces at the start of each line is converted — every full "Spaces per tab" becomes one tab and any leftover spaces stay after the tabs (with width 4, six spaces → one tab + two spaces). Spaces inside the line are left alone.

「制表位对齐（智能）」是什么？What is "Tab stops (smart)"?

按制表位（每「空格/Tab」列一个）处理整行，和 unexpand -a 相同：一串空格只要到达下一个制表位就换成 Tab，所以对齐的列在任意 Tab 宽度设置下仍然对齐；正好落在制表位前的单个空格（后面不再跟空白时）保留为空格，已有的 Tab 不变。It works on the whole line using tab stops every "Spaces per tab" columns, like unexpand -a: a run of spaces that reaches the next tab stop becomes a tab, so aligned columns stay aligned. A lone single space just before a tab stop stays a space, and existing tabs are kept.

换行符会变吗？Are line endings changed?

会统一成 LF（\n）。They are normalised to LF (\n).
