Option --debug-headers doesn't always work

[robertbruntz]

Describe the bug

Running check_ssl_cert from Bash with the "--debug-headers" flag ("Store the retrieved HTLM headers in the headers.txt file") does not always produce the expected headers.txt file. E.g., "./check_ssl_cert --debug-headers -H github.com" does not produce the file, whereas "./check_ssl_cert --debug-headers --all-local -H github.com" does produce the file. I have not tested many other flags to see which ones do and do not cause file production. "--all-local" does; "-v" does not.

To Reproduce

1. Clone the repo
2. Run "./check_ssl_cert --debug-headers -H github.com"; should not produce headers.txt
3. Run "./check_ssl_cert --debug-headers --all-local -H github.com"; should produce headers.txt (with the HTTP response headers from github.com)

Expected behavior

Running check_ssl_cert with the --debug-headers flag should always produce headers.txt

System (please complete the following information):

• OS: Linux
• OS version: 3.10.0-1160.108.1.el7.x86_64
• check_ssl_cert version: 2.81.1
• OpenSSL version (openssl version): 1.0.2k-fips
