问题
Combining svn diff --ignore-eol-style and --ignore-all-space is not working:
$ svn diff -x -w --ignore-eol-style -r 1143:1177 somefile
svn: invalid option: --ignore-eol-style
And,
$ svn diff -x --ignore-eol-style -x --ignore-all-space -r 1143:1177 somefile
Only executes the last option: ignore-all-space
Anybody dealt with this before?
回答1:
The svn command seems to honour only one -x option. This means, you must/can combine all options into one argument:
svn diff -x "-w --ignore-eol-style"
I did not test whether this is also true for external diff-tools.

You can use external differencing tool with appropriate options (diff-cmd option in SVN config). Check this. Then you have freedom to set any diff tool and provide arguments to it. You can also use it directly:
svn diff --diff-cmd /usr/bin/diff --extensions "-b" -r 1143:1177 somefile
where -b to ignore white space at line end and consider all other sequences of one or more white space characters to be equivalent,
