Well, if we didn't have "Include", mixing one's .ssh/config out of 
globally-maintained and local/individual files (without using some 
preprocessor) would be a nonstarter ...

... wait. Do you mean to replace every single "ProxyCommand nc ..." line 
in the global file with an "Include my_proxying_oneliner_for_site_XYZ"?

[runs test]

(... OK, need to keep that one-liner in a subdir disjunct from the 
*existing* wildcard "Include"s, and "Include" takes pathes relative to 
~/.ssh, not relative to the file where the "Include" occurs ...)

It *works*, but I wonder how *scalable* that approach is, with read()s 
zig-zagging between config files like a March hare ... ?

Kind regards,
