io.cpp "vgridshit" literal string should be "vgridshift" ?

Example of problem

// io.cpp line 7777 misspelling of vgridshift as vgridshit 

Problem description

the code's intention is clearly to return false for the string "vgridshift", but does not because of the misspelling "vgridshit". The subsequent loop around proj_list_operations() finds "vgridshift" and return true.

if the behaviour is actually correct then the "vgridshit" literal should be removed.
