我可以通过三种方法来实现所需的编辑看，下面按我个人喜好的顺序列出.
There are three approaches to implement the desired edit that I can see, listed below in the order of my personal preference.
使用前置原子匹配语法的替换(见 :help \@):
:%s/\%(^ *\)\@<= /\ /g
如果命令的简洁性很重要，可以缩短它使用非常神奇"的模式(见 :help \v)通过改变非捕获组 (:help \%() 到捕获组:
If brevity of the command is crucial, one can shorten it
using the "very magic" mode (see :help \v) by changing
the non-capturing group (:help \%() to a capturing one:
:%s/\v(^ *)@<= /\ /g
一个两阶段的替换，在前导之后分割一行空格，替换这些空格，然后重新加入该行:
A two-staged substitution that splits a line just after the leading spaces, replaces those spaces, and rejoins that line:
:g/^/s/^ \+/&\r/|-s/ /\ /g|j!
另一种两步替换，替换每个前导文本中未出现的某些符号的空格，并更改那个符号到 :
:exe "g/^ \\+/norm!v//e\rr\r" | %s/\r/\ /g
