Too bad nobody has reported this in the last several years (we've been using this 'xargs ... grep' scheme since before the introduction of xref-matches-in-files in 2019). I was kind of expecting xargs to know MS-Windows' command line limits, i.e. from its manual: The largest allowed value is system-dependent, and is calculated as the argument length limit for exec, less the size of your environment, less 2048 bytes of headroom. ... xargs automatically adapts to tighter constraints.
