I've experimented with various macros to undefine/temporarily disable 
shortcuts and found that most convenient variant is to insert this 
catcode changing into \typefile command. Why not to do this for every 
command, that accepts path parameters? This slows process down too much?

But this is just an afterthought.

I think that \defineshortcut commands are most useful inside some 
environment (start/stop pair). So it is possible to have such 
environment that restores back all catcode changes (or other variable 
changes) made inside it (like local variables in some programming 
laguages)? This can have many other uses.
