Found 2 big problems with this dialog (Options -> Customize Macro menu...):

1) The keyboard accelerator key 'C' is used for both "Menu &Contents" and "&Command Line". Since "Command Line" is last, Alt-C goes there. Need to make them unique!

2) Long file pathnames entered in the "Command Line" with enclosing quotes have the enclosing quotes stripped off when exiting/restarting the program. Example:

"C:\Program Files\GTEdit\script\macros\foo.c"
becomes
C:\Program Files\GTEdit\script\macros\foo.c

and then choosing the related macro or toolbar button results in an error msg that "C:\Program.c" couldn't be found. Please fix!
