Extra whitespace in some configuration directives causing error

[porjo]

Describe the bug

Putting more than one space or tab between some configuration directives and their value causes an error.

For example:

SecAuditLog /usr/local/apache24/logs/modsec_audit.log

If I put 2 or more spaces between SecAuditLog and /usr/local... (or any number of tabs) I get this error:

nginx: [emerg] "modsecurity_rules_file" directive Rules error. File: /usr/local/apache24/conf/modsecurity_rules.conf. Line: 34. Column: 55. Invalid input:  SecAuditLog  /usr/local/apache24/logs/modsec_audit.log in /usr/local/nginx-1.10.1/conf/nginx.conf:48

Other configuration directives don't have this problem. For example I can put many spaces between SecAuditLogFormat and JSON

Expected behavior

Extra whitespace (within reason) should be permitted between directive and value as this can assist to make the configuration file easier to read. Also, behaviour should be consistent for all directives.
