  Log Message:
  -----------
  parse_content_length(): Fix integer overflow edge-case (OSS-Fuzz)

This completes commit 7cab422e2f, where it was still possible to cause
an integer overflow even after the fix, with input such as 2147483609,
due to missing parentheses in the number equation.

Fixes OSS-Fuzz#52112
