Remove semicolon following GLOBALS macro in the few commands that had one, as well as unneeded semicolons following one line cp functions

[E5ten]

These cause a -Wextra-semi (if it is enabled) warning for every inclusion of globals.h, due to a double-semicolon following the structs for these commands' global variables. Remove the unnecessary semicolons.

Does this change actually accomplish anything?

...it would mean i have no chance of winning the pedantry award for 0.8.4 :-)
