* doc/invoke.texi: Remove leading dash from @opindex entries
variable references.
The @option{-fno-common} option specifies that the compiler should instead
-place uninitialized global variables in the data section of the object file.
+place uninitialized global variables in the BSS section of the object file.
This inhibits the merging of tentative definitions by the linker so
you get a multiple-definition error if the same
variable is defined in more than one compilation unit.
