Pull request overview

This PR updates scripts/spacecheck.pl to reduce the risk of accidentally committing/merging extremely large text files by adding a per-file maximum line-count check.

Changes:

• Refactors eol_detect() to use precomputed CR/LF counts instead of scanning content internally.
• Adds a max_lines threshold (10,000) and reports an error when exceeded.
• Adjusts the mixed-EOL error text to hint at possible binary content.

Comments suppressed due to low confidence (1)

scripts/spacecheck.pl:144

• After removing the unused $content parameter from eol_detect(), update this call site to pass only the CR/LF counts.

    my $eol = eol_detect($content, $cnt_cr, $cnt_lf);
