078603bCompare`--filelist` stopped accepting Windows CRLF line endings in 165e52c ("first implementation supporting Process Substitution", facebook#4349). That rewrite reads the list into a buffer opened in binary mode and splits it on '\n' alone. Previously the list was opened in text mode, where the Windows CRT translated CRLF to LF before the parser saw it, so stripping '\n' was sufficient. In binary mode the CR survives into every path: zstd: can't stat a.txt : No such file or directory -- ignored The '\r' is invisible in that message, which makes it awkward to diagnose. Strip a trailing '\r' when the line pointers are built, but only on Windows, where CRLF is the native line separator and a '\r' cannot be used in a filename. Elsewhere '\r' is a legal filename byte and is left alone, so behaviour on those platforms is unchanged. This restores the pre-regression behaviour exactly, on every platform, without adding a new one. Adds a playTests case, guarded to Windows, that fails without the fix.
