All, I just upgraded to version 1.8 of Yegappan Lakshmanan's convenient grep.vim[1] plugin. As part of the fix in version 1.8 for handling spaces in file and path names, the `--null` switch was added to xargs. Unfortunately, the OS X version of xargs doesn't support the long spelling of this argument, though it does support the short spelling, `-0`.
Could the grep.vim script be modified to use `-0` instead of `--null`? I believe the `-0` option is more portable than the `--null` option, though it doesn't seem to be universally available[2]. It is available on OS X and systems with GNU xargs (Linux, *BSD, ...), but a quick Google search indicates that it's not fully portable. For example, Tom's Hardware page shows a comparison of xargs options across many operating systems[2]. Support for `-0` is missing on AIX and Solaris. The Open Group web page[3] doesn't mention the `-0` flag. Given that the `-0` option for xargs is not universal (nor, for that matter, is the `-print0` option for find), perhaps the grep.vim script could offer a variable to configure the use of the `-print0`/`-0` combination. As the script stands, users can work around the issue by disabling the use of xargs entirely (via the Grep_Find_Use_Xargs variable) but this comes at a performance penalty.
