间距

¥Spacing

变量键和值周围的前导和尾随空格将被忽略，除非它们被引号括起来。

¥Leading and trailing whitespace characters around variable keys and values are ignored unless they are enclosed within quotes.

例如：

¥For example:

   MY_VAR_A   =    my variable a
    MY_VAR_B   =    '   my variable b   ' 拷贝

将被视为与以下情况相同：

¥will be treated identically to:

MY_VAR_A = my variable a
MY_VAR_B = '   my variable b   ' 拷贝
