wc: unexpected stdout diff for multi-file output padding

[matt-dz]

Summary

QA comparison found that rshell's wc output column padding differs from GNU wc for multi-file input. The numeric counts and file ordering match, but the stdout differs byte-for-byte because GNU pads count columns more widely.

Sanitized example

Command shape:

find <directory> -type f | sort | xargs wc -l

Expected

wc should match GNU wc output formatting for multi-file counts, including the leading column padding used when filenames and a total line are printed.

Notes

This report is sanitized: it omits local artifact paths, run identifiers, and scenario-specific metadata. The finding was deduplicated across the QA run before filing.
