openssh bugs - Jul 2015 - [Bug 2431] New: Form feed is not treated as whitespace in config files.

https://bugzilla.mindrot.org/show_bug.cgi?id=2431

            Bug ID: 2431
           Summary: Form feed is not treated as whitespace in config
                    files.
           Product: Portable OpenSSH
           Version: 6.9p1
          Hardware: All
                OS: All
            Status: NEW
          Severity: trivial
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: andreas.seltenreich at credativ.de

Form feeds (aka \f, \014, ^L) are sometimes used to separate logical
sections in bigger files.  Support for navigating files based on these
sections is common in editors.  For example, vi can jump to the next
one using ]] and Emacs using C-x ].

I am used to insert them in all kinds of config files to ease
navigation as soon as their size becomes unwieldy.  To my surprise,
inserting one in ~/.ssh/config produced a syntax error instead of
treating it as whitespace, as every other config file parser I've
come about until now does.

allow \f at EOL

This allows \f characters to appear at EOL (well, strictly as part of a
whitespace sequence at EOL). I don't think it makes sense to allow \f
as a token-splitting character.
