    fullgaps but with toggle function and Gap struct
    
    [Alt]+[Shift]+[=] toggles gaps. Re-enabling gaps will return to the
    previous gap size.
    
    [Alt]+[Shift]+[-] resets gaps to default value in `conifg.h`.
    
    The Gap struct is defined as follows:
    
    typdef struct {
            int isgap;
            int realgap;
            int gappx;
    } Gap;
    
    See `void setgaps(Arg *arg) {...}` for how this works.

+The following patch allows for gaps to be toggled, and also uses a `Gap` struct
+to contain the gap information, in anticipation of this being used with
+[pertag](../pertag/). (To use this, apply the patch *instead* of the default
+fullgaps patch.)
